The crop looks great, and that is one beautiful rail. Very nice feet out landing pose and wing position. The orange reflection on the blue water makes a nice bg.....but I would defiinitely get rid of the dark weed bits, and I think a shadow/highlight adjustment will bring out lots more detail in the dark areas of the underwing and chest. Well captured.
It's nice to break away from "conventional". I don't think this crop would work as well with out the great diagonal reflection that you've captured. I also think getting rid of the reeds at the bottom of this image is a must. Nice work.
