This one i did script out a bit. Sometimes i wing it... but usually i film myself a few times doing whatever action i want to animate. Then after i cut what i want together, i use that footage as video reference.
Hohoho, I'm always filming myself as well, pretty embarrassing. The "webcam room" animation studios have must be silliest and most important place of the whole thing!
Great work man. I love how you had the shield role around him on his first attempt at picking it up. It makes sense and is cute, too! Good luck in the contest.
