I did an ork warboss with plasticard armor not too long ago.
I highly, highly recommend you buy a multi-size leather punch. You can use it to cut out tons of circular rivets to add details to your panels. Even better is the sheets with the lots of holes punched into them can be added on top to get a nice scrap armor junk aesthetic. The punch is a great modeling investment.
Using cut up plasticard rods as rivets does work but it takes ages, and you don’t get wonderful damaged armor panels to use as details.
With the plasticard try to cut some pieces with uneven and slanted edges, to really reenforce the haphazard construction.
If you have access to any broken small electronics like computer mice or speakers or a remote control, tear it open to look for interestingly shaped pieces of plastic that won’t be easily recognizable.
With greenstuff, using silicon tipped tools is best, but if you don’t have them you can get by with some metal framing nails kept wet to use as a tool to pull the greenstuff and blend it with the body of the toy animal.
Thanks! I live in Japan so I can't really say what they would be but here is a similar set I found just now https://www.amazon.com/Carving-Whittling-Carpenter-Sharpness-Plastic/dp/B09N2KCCWD/ref=mp_s_a_1_5?crid=VEBWZVXC4IZE&keywords=%E5%BD%AB%E5%88%BB%E5%88%80&qid=1650926388&sprefix=%E5%BD%AB%E5%88%BB%E5%88%80%2Caps%2C260&sr=8-5 These are terrible quality though and I'm just using them for minimal tasks.
Try using the guns of ww2 or ww1 or cold War era tanks near the harchers on the back but keep the foot and comder harch because I can image this with the Tarkin doctrine was rooted in Tarkin's theory of "Rule by Fear"—the contention that overwhelming displays of force, rather than force itself, were the most effective means of maintaining internal security and the loyalty of vassal worlds.
Because I can imagine seeing this thing running at on battle field like the britsh tanks did in the treachs in the great war caseing civilians and hearing the machine guns blazing at enemies of War in theory there be a mancinence gun the top harch but not one big f**k of gun on top as that would look unrealistic.
My inspiration for this idea came form theM4 Sherman (there's my inspiration photo)

The LEDs separated into groups that can be cut / separated and powered with a pair of packs (4 batteries).
You’ll need supplies for warping, bending, cutting and welding plastic. Heat gun, soldering iron, hot knife, plastic welding strips, an actual plastic welder would be nice but they are expensive an unnecessary as a soldering iron and torch is good enough. There are some video on YouTube of how to plastic weld with a soldering iron and a pocket torch. I’d recommend the Dremel torch it is a torch, soldering iron, hot knife and heat gun all in one.
