I kind of like it like this. Maybe put other figures in the background backlit so there's just shadows. Particularly characters who have obvious or recognizable shapes (like Goro in Mortal Kombat).
I love your shoes. I wish I could draw shoes like that. I will probably shamelessly copy that.
One note, the chick who's doing the squat, her left thigh looks a little on the over-muscled side, but that may be the style of the characters (bazooka breasts and waifish waists).
Good job though.
