Excellent
I guess I'll get my peeve out of the way :D
I think that her guns look a bit too flat. Well, I guess, her "left" gun anyway, but I suppose it is 'cause of the angle (That, and her guns are already flat to begin with :D ).
I like how you used warm colors in the back which made her cold colors stand out. I also like how there's always an angle when you draw rather than just flat on the drawin' board. I'm imagining her jumping off of the fence, sideways rather than directly down or over the fence. Thinking that way, her pose doesn't seem out of place :D
Overall, I like it. Didn't imagine that you'd do a BlazBlue one! If you have it on the PS3 and want to play sometime, lemme know! :D
