Hey, nice work! That’s a definite improvement.
The lowest hanging fruit that sticks out to me is the depth perception around the torso. If I didn’t already know what the character looked like, I might have a hard time perceiving which parts are the arm vs. shoulders vs. chest. Like, when I zoom out, it’s possible that the abdomen swells out closer to the camera than the arm, except that I know it definitely doesn’t lol so I choose not to see it that way. I don’t have any exact solutions for this (my lack of proper art training is showing) except to continue tweaking things and keeping an eye on that.
I noticed that the darkest outline color isn’t in the pallet, and the brightest two blues seem interchangeable to me and can probably be merged into just the brightest one. That’s up to you if you want to darken the back leg – could definitely work if done well.
It probably sounds like I’m being really picky, but that’s just because it’s getting harder for me to pick out the flaws since the design is more solid now. At this point you could probably experiment with a few different styles depending on what type of game you were thinking of dropping this sprite into. For example, the new outlines and clearer blues give it more of a cartoon look, so you could flesh that out more, or switch to a serious and gritty tone, or whatever you want. Maybe a Zero Mission vs. Fusion vs. Super style could be fun! Or if you want to get what you have torn apart even more, you could post it on some forums that specialize in pixel art and see what happens. :O_O:
Anyway yeah, keep it up.
