Paladin of Brass and Steam

Okay, here's the colored version of the line drawing I did earlier. I toyed around with colored lines, I kind of like it, but it still doesn't feel quite right. In general I'm pleased with this one, but I could use more help, comments, suggestions, etc.

Line: .7 pencil
Coloring: phothshop CS2

edit: the brass structure in the background is an obelisk, and the sides aren't going up at 90 degree angles, they're a bit slanted. I realized this at the time, but of course it doesnt come out in the small section shown, oh well.
