Really interesting use of colour, I like it. The only constructive criticism I can think of is that it is a little busy. I think the second Alice (the one on the left) might be a bit much. A place for the eyes to rest wouldn't hurt. Still I really like what you've done and of course it's your work so to each their own.
Really good lighting and effects. I am kinda thrown off by how cluttered it is though. There is just too much going on. That may be different as a wallpaper though. Either way, nice job. KIU.
