I like the gliding pose and eye contact and this might work really well as pano crop. I would also try to get more details in the shadows and add a bit space on the left.
I like the colors and the slight head turn, Stuart. This image cries out for a pano crop, IMO. I'd also like to see more room both left and right - an easy fix with this clean background. You might also try to pull more detail out of the dark shadow.
Very nice pose. It reminds me of our Swamp Harrier as they also look similar in wing position as they glide above the swamps looking for prey. Dark areas mentioned. :)
