You did a very nice job coloring this picture, very vibrant and fitting for a Mega Man character. My one comment is on the eyes which seem those of a tired, perhaps old man, but in a strange way that is kind of fitting for him. Nice work.
exCUSE ME? NapalmMan has to be the greatest robot master ever created. The tank treads only add to his awesomeness (ever hear of rollerblades? yeah, a good thing). Not only that: Missiles, Torpedos AND Bombs. He'd have to be the most ridiculously OVERpowered of any robot master, thus the strongest.
