nice attempt, too much negative space unless you were going for minimalism, good color, nice dof, light flat, blacks need help, whites ok, comp needs work, overall ok
Lovely colours, but the image doesn't seem to have a real centre of interest. Also, I would suggest cropping the foreground by about half. The reflections in the front part of the foreground don't really supply enough interest to justify the amount of space they occupy in the frame.
my only think I think you may could have done was clone out that little floating thing on the water's surface to not have a break in the mirror effect. Nice shot and wonderful colors!
