This looks good to me, it gives a neat effect because at first I thought it was a reflection and wondered how you weren't in the shot. I agree with router on things as a critique, but they are just barely noticeable.
I like it, though I think it would be more striking with a richer blue. The window bars look find but it appears as if ther eis a bit of an USM halo around them. Also looks like it is very slightly slanted from left to right. Just enough to be noticeable. Overall really nice photo.
