I like the dynamic moment you've captured here, Stuart. Cool wing position, and good view of the fish. The clouds in the sky add a bit of interest.
Not sure but you might have a hot spot on the leading edge of the left wing.
An image with a lot of impact, very sharp detail in plumage and eyes, cant decide if I would like the image better with or without the bottom greenery, but i do think a bit more canvas on the top would be good
The image has a painted look to it, very nice. Good colours, perch, vegetation at bottom. Love the wings-up pose. I agree with Phil for a bit more room above...
