This wall is pretty attractive. I actually love the angle of the chara.
Green-themed... Not bad but it might be nicer if there's more colors

Awesome! I love how the colors blow up in your face, shaking all your senses. Yes, too much green, but it works for the dynamics of the pic.
I like also how super saturated green gets splattered right underneath the character, giving the idea that all the action in colors starts from the shadows where she lies... ok, maybe I am pushing too far here :P

I would have liked however to see her red tie colored differently... I think the red stands out too much that it looks that control in colors got slippery in that point. Maybe a light green (closer to yellow) would have done well for the tie.

Good job overall!
