Reminds me a lot of a book I have: Urban Watercolor Sketching: A Guide to Drawing, Painting, and Storytelling in Color
I've done a few general sketches but really need to be consistent at it. How often do you find yourself sketching on average?
First of all, go for it!
Second—well, here I would usually talk about great teachers and classes locally, but instead I'd send you to YouTube, where there are a lot of great teachers. [The Mind of Watercolor](https://www.youtube.com/user/mindofwatercolor} is very popular.
I also really recommend Shibisaki for beginners. His approach is really uncomplicated and he's got a Bob Ross-level of chill. He teaches in Japanese, but with subtitles it's easy to follow along.
As far as books that I've found helpful, I can't recommend Urban Watercolor Sketching strongly enough. Felix Scheinberger is a former punk rock drummer, and he gives watercolor painting that same edginess, energy and sense of fun. Covers a lot of fundamentals of theory, technique and materials.
Also, it can be really useful to sketch with other artists, whether online or in a real-world group. I organize the Sunset Sketchers…we're out every weekend (with masks and social distance) on the west side. Sketchers at every skill level. Good way to pick up tricks and tips. A really supportive group.
Aw heck! I think anything I do that comes out well is an accident. But I'll give you two resources that have been particularly helpful to me -- two teachers with very different approaches.
First is Urban Watercolor Sketching by Felix Scheinberger. He's a former punk rock drummer who brings that energy, edginess and fun to watercolor.
Second is the great Shibisaki-sensei. His YouTube videos show you an easy approach to beautiful painting. And he's extremely chill, the Japanese Bob Ross.
Third, watercolor/sketch a lot. Bring a watercolor sketchbook, a small paint set and a water bottle/jar with you wherever you go! Paint everything. You'll start teaching yourself just from doing it.
