Astonishing X-Men - Colors

I'm a bit disappointed in how this one came out. I liked the initial sketches, but somewhere in the inking and coloring stages it lost all its energy. I kind of feel like this one had a chance, but I lost it on the operating table. I'll have to make something really dynamic to make up for it.

*edit* Fixed Frost's hairline - thanks all! As to why I don't like it, I kind of prefer the sketches (I've uploaded to my scraps). I do like how Colossus came out, though.
