I'm not a personal fan of stages like this. Ones where your moving around, but there are sprite edits in the background just staring at you with no animation at all.
Sabertooth, the guy wolverine wants to kill is RIGHT there, but they seem to enjoy staring at each other and the fight more xD
Also there are no shadows, and little if any animation/layering.
Sprite edits are not bad though, like the SNK bit on them.
