Its a nice shot, i tried to look at the exif info on flikr but its not there? there is a fair amount of grain in the colour suggesting a high iso, you could maybe try a lower iso and a longer shutter time to reduce that effect.
Also i'd recommend carrying a lens wipe with you at all times, quite often people forget to wipe the lens before shooting. I see there is what appears to be a rain drop or smudge center frame an inch up from the bottom on the water, and there is another smaller one right side a third of the way down. Easily fixed with the clone tool in ps though.
I do like the colours and its nicely framed.
