Lovely definition of the bird against the BG and I like the water droplets on the back. I agree re cropping - especially from above - I think this would work well as a pano crop like this. Mild colour cast neutralisation. Sharpening could be backed off a bit as there are prominent halos but I think this is a lovely image.
Thanks Guys for the comments, much appreciated. I will check out the colour cast and sharpening. Interesting suggestions about cropping a bit tighter; I was a bit worried I had over cropped since I had cropped already. Still getting used to the extra pixels in the 50D I quess.
