A couple of things jump out at me in this shot,
1. the blown hightlights around the sun, I know its very hard to control when shooting
directly into the sun, maybe some kind of a filter (nd or polarizer) would have helped a
little?
2. There are plenty of little spots either from dirty sensor or on the lens.
Composition wise it is a little bit lop-sided with all the interest on the left of the frame.
On the plus side the colours are nice and crisp the focus is good and the HDR isnt overdone.
