I think he's still leaning a bit too forward. The fist clenching and posture doesn't exactly look natural. Perhaps you should consider repositioning the legs. You should also consider reworking those shoulders. They're definitely not even. The pants shoulde definitely have more shading and shouldn't a shadow be cast from his belly? The light source is really confusing here. I also think you put the brightest shade on his body in all the wrong places. That may also be why the light source gets confusing. Looks like you worked on each part of the body separately without really considering the sprite as a whole. The palette you chose for the body is pretty good though. Overall, it still looks like a work in progress to me.
K thanks for the crit. I'll try to fix it.
