I found Perspective by David Chelsea useful. It's aimed at comic artists but the techniques are exactly the same no matter what medium you're using.
The hardest part will be the foreshortening. But once you get that sorted you'll be on your way.
Perspective is one of those fundamentals you need to learn, just like shading and anatomy. It does indeed add a shittonne of work to your piece. People will notice when it's not there or done badly. They won't notice when it's there and done well. It sucks but it needs to get done.
There's a book called Perspective for Comic Book Artists by David Chelsea I recommend. There's a decent chance your local library system has it. The rest is just practice.
Clip Studio Paint has a lot of very good perspective rulers and it does everything it can to idiot-proof the process. IMO it's far superior to any other option for making comics and comic-adjacent art, and it's a one time purchase.
These days I just drop it into Clip Studio Paint and trace what I need. :D
In my defense I did learn to do perspective by hand back in the day. It can be hard as hell once you get into curved surfaces. I did find David Chelsea's Perspective! book to be pretty useful as a reminder on how to do it.
But even with digital help I still lay out the perspective lines so everything I add to the image, or move around, looks like it's in the right place. Even though I'm fairly confident I know enough nowadays to fake it some habits die hard.
If you're serious about learning perspective, this is a really good book that isn't too terribly academic.. Nail down perspective, nail down anatomy, then you can draw heads in perspective all day long.
This is an instructional book on perspective, in comic book form. It's a little goofy, and the guy is completely ripping off Scott McCloud's style (and admits it), but the book covers some concepts in a more accessible way than other, more conventional books that I've read on the subject.
I feel like everything I've read, McCloud's really the best source
drawing words and writing pictures by jessica abel and matt madden I liked, two volumes and beginner friendly I think
the subbredit comic_crits is good, they got a lot of good stuff in their sidebar
Perspective for Comic Artist
cartoonist kayfabe, history and commentary on traditional comics
doki doki drawing
mckay and gray
100 days of making comics is also a good tag
twitter is really a good place to find other artist too, it's sort of a same there isn't a social media with a twitter-like format but with kickstarter and portfolio side bar tabs .
I follow a lot of the UK Indie Comic scene on twitter -if there's any artist you like, see who they like on twitter too
I used these two books
I use clip studio paint, and use the perspective layer and use of the straight lines (shift) and these straight line brushes that snap straight. It has a lot of different ways to do straight lines.
If I start wanting to tear my hair out, I use this cube from the CSP Assets page and you can toggle the perspective ruler on and off b/c it's a 3D object. This is actually the quickest way I can manage 3pt perspective in a scene but I always try to place the lines first but I have trouble placing the horizon line sometimes.
I also use Paint Tool Sai 2, a lot of people as far as I can tell, don't use the second version but I find using the shape and perspective rulers more intuitive
I think the funniest thing about having learned perspective is how much the cone of distortion is present. I would set up a picture and realize I need to "roll" back the perspective to match the photo I was referencing.
I always enjoy using SketchUp when I need to quickly visualize a scene. I also use this to check my horizon line since I don't place it right.
I think you have the fundamentals down, just a matter of grinding it out, figuring out what you like best.
I'm a big fan of Perspective for Comic Book Artists by David Chelsea
I've owned a few perspective books and his chapter on 3pt really pieced it together for me. His chapter on circles and cyclinder, I've yet to really read since it seems daunting...
Also, backgrounds can also be best be thought of as a shadow box: background, middle and foreground. Etherington Brother's tutorial . Just pointing this out b/c it's something I tend to forget and the big bold thumb shapes really clarify a lot for static images.
Artstation has a lot of CG and concept industry professional art but more importantly they also show their process a lot of the times too. You can search for environments and thumbnails, I'd say the sketches and thumbs might have the most important info than the finished products. I have an account on there, but I mostly use it for favorites and inspiration from contempoary peoples.
I also recommend making a pinterest board with movie stills & comic images to help grease the wheels. If you don't quite get it, Pinterest algorithm is good at pulling like images, I use it for that with anatomy, everyone draws a little different and I like seeing examples.
Moebius' comics is also amazing, but just remember it's really hard to get to that level; but as a means to see what simple lines and negative space can do. I want to see some horizons myself, is that makes sense.
I find Jesse Hamm's tips twitter a gold mine for great comic advice.
Oof! Perspective is one of those things that has entire books with lots of pictures written about it, and not really something that can get covered easily in a Reddit comment thread.
Assuming that you're trying to "reverse engineer" the photos you've linked to: Print out the images and take a ruler to the edges of each object and establish where their personal vanishing points are. Draw a line through those vanishing points to generally establish your horizon. (Or do it in computer if you're working digitally)
This won't be 100% because camera lenses have distortion we never pick up on. Then again so do our eyeballs. But the thing in representative art isn't to copy reality. It's to make it look like it's copying reality. You're performing a confidence trick. A visual slight of hand. Convincing people that they're looking at a pipe when they really aren't.
Working from your imagination isn't too different than the one and two point perspectives you said you've done before. But one thing to remember is that in most cases your vanishing points are so far off your paper... and even your table... that there's no point in trying to rule them out. That's when you fake it. This actually takes a bit of practice to do it convincingly enough, but the audience won't notice unless you really screw it up.
You generally have to make sure it's consistent with itself. This is why you should try to visualize your objects as sitting inside boxes. This is a lot easier with furniture since they're generally box-shaped anyway. But approaching it like this can get you in that "close enough to fool people" range I've been talking about.
There are plenty of books and I'm sure other users will have a good list of them. I found Dave Chelsea's Perspective! For Comic Artists helped me a lot back when I was working with pen & paper.
Then I learned how to cheat. :)
A fun and easy book that covers most of what you need to know and practice is "Perspective for Comic Book Artists". I Highly recommend it!
