Very observant, I'm glad those details show through.
Hey Big Fan, thanks for all the detailed comments - I really enjoyed reading them. This is one of my earliest animations and I've learned a lot since making this. The movement of the arm and body is robotic and follows the 3D reference too closely. The lines are quite sketchy - now and days I work at high res and down sample for the final product to minimize the appearance of errors. I have also learned that it is much easier to refine your key frames before tweening instead of sketching out a million frames and then refining. It'd be much easier to start over than to attempt to salvage the frames here. I might just do that, though :)
