Well my critique will be simple. The scene is pretty awesome. The only thing I think need a lil touch are the two upper girl faces; I think there is a problem with the angle of the heads an the lights. And the other thing is about the blue haired girl. The flow is not convincing at all. And the last thing is the left leg angle of the blue haired girl; it has to be fixed by the knee area. Just a lil bit, because the way the highlight is placed don't really help the angle visual effect.
But generally I think it its a great illustration, specially by the action and movement.
