...So I take it you aren't a big Metroid fan, considering you apparently keep getting her name wrong.
Haha, but no worries, this is a pretty bad-ass drawing. Kraid looks especially awesome, notably the spikes jutting from him. They look more rocky, as it seems would make a bit more sense, compared to the more flat platforms from the game. His face and teeth are also great. Very menacing looking.
Samus isn't bad either, although the perspective is a bit skewed. Considering her shoulder pad is normally parallel to her helmet, it doesn't make much sense for her helmet to actually be showing some distance in front of it. The rest of her body looks fine, it's just the head that's a little incorrect. It would probably be more around, halfway behind the shoulder pad, and halfway off the picture altogether. The placement isn't really important, as it wouldn't be visible from this angle, period. Pretty awesome glow effect on her suit, though. And the colors are spot-on.
If only they had had the time to put him in Metroid Prime, I think we would've seen an epic fight with stuff like him biting at her, slashing at her, and trying to stomp her into the ground. Oh, and tail whipping.
