Hi Ross,
I really like the concept you had for this image. I wish we could see the birds' eyes although I understand that he is trying to find a spot to land! If you are not against cloning I would clone out the flying speck of a bird between his legs and the bird wing on the RHS of the frame.I think you can tease out a bit more detail in the underwing with fill light or S & H tool,
