Wow. Colorful, detailed, and quite lively. Bass looks like he's ready for a fight, Proto Man looks...content I suppose. It's hard to tell what that robot has on his mind (you captured that aspect well here), and Mega Man/Roll just look nice. Roll seems to want to hog the spot light (what sister doesn't ^_^), and Mega Man seems like he's being crowded here. Hmm...I wonder if that's Bass laughing at Mega Man right there.
