The punch animation's looking better! I think you need to hold on the extended arm longer though.
The angry eyes in the punch animation are much more readable, though I'd lower the eyelids even more. You didn't add the dark bit in the running animation, so that still has U-shaped eyes.
Some suggestions for colour tweaks:
- more contrast on the do-rag, as your shadows were practically invisible
- reused the shadow colour for the blue in the eyes, I think the extra contrast helps. If you want low contrast, then just don't use any blue at all, it doesn't seem needed.
- you went a bit
too sub-dued with the green spots, you could afford to bring back more of their greenness. In particular, it makes no sense for the green in the shadows to be lighter than the shadows, since the spots are supposed to be darker than the skin.
I tried editing the punching animation:
I removed one of your punch-forward frames (the fewer frames, the faster/snappier it feels), and instead added an extra frame at the end of the punch, and held it twice as long as the others. I think this makes it feel stronger. You could hold that frame even longer, such as 3x or 4x as long as the others.
I also tweaked the eyes in this edit, while I was at it. All I did was move a blue pixel down, and it looks angrier.
I didn't edit the anticipation, but I do think it would benefit from being longer.
