I am digging this style so much! As someone else mentioned, if you want to go a little further you can add in some edge highlights for wood cracks and such to get those nice edges pop ( you done that on the asset with the blue pants logo which makes those details really pop).
Couldn't find anything within an admittedly short search for a flipbook shader in blender so I setup some base functionality for one with some vectors. Figured I'd share in case anyone else was looking or something similar. Mix it with some masks for some fun effects.
