The animation is very smooth, the palette is vivid and interesting, and you very efficiently define clean, readable forms in limited space with said palette.
I loved the light and that smoke coming out of his mask! ^_^
I'm no expert on pixel art, but dare I say that the colors are amazing on this! Such a great piece.
That is awesome! Would totally play this game if this ever happened. 
This is so awesome! Attention to detail couldn't get any better.
Pretty solid animation. Would love to see this in a videogame 
Cool, remind my childhood time when playing "Contra".
That's the most perfect sprite related animation that I ever see. I would love to see it in a game.
Love it. Prolly my favorite piece on this site. The gas from his mask is a really nice touch.
Perfect! I´ve learn a lot with this ^^... animation, lighting and nice palette, 235 favs are not enough ; )
