I find this painting to be quite compelling! The character has a great design, yet with more expression and character than most designs of that style. I think M.C. Escher would approve of the background, you've taken it more into sci-fi, and it's far more menacing. I like the one bit of warm color down the lower path.
The figure in the foreground is very interesting, but I think the background is where the real eye-candy of this piece is. Very dynamic, very mind-bending, and very beautiful!
