I agree with Mesoam. Its a gorgeous shot, but the blue is a little overwhelming. Try cropping out some of the foreground, say, just where the tree reflection starts on the left hand side of the photo downward ccrop out. You'd still have a nice shot, but not as blue. Just my two cents worth.
I'd put the sky back in. The blue on the bottom looked a bit heavy before the crop, but with the sky back in with the bottom cropped it would have a nice look.
