Really expressive animation and fluid movement. Really nice. I just think the left arm could have a smaller vartiation of space; it really goes ahead of the character all out of a sudden. It's good because it's unique, but after seeing it a lot (and judging the player will see this animation a lot too) it seems he's always punching the air..
Anyway, excellent work, 6/7. Oh, I'd like to see his concept too, Homem Incapaz is an interesting title for a hero o_O
Man this is a gem!
The preview just doesn't do it justice with the black outline.. I would get rid of the black outline there if I were you :D Besides.. The animation is under 100x100, why not use just one file?
