This great blue lost patience with posing for me, and took off with a squawk. Shot in late afternoon light.

That looks like a seriously ticked off heron!! Very dynamic screaming pose, although I do wish the far wing's feather did not touch the neck. Nice details, well exposed. Some may find the vertical lines distracting but I actually like them. I could see a version with the heron a bit lower in the frame and with more room in front.
Ian and Daniel made some good points. I would only add to keep photographing this guy. Just a bit better head angle on this one would have been real nice.
Very nice!! I agree with some off the bottom and a little more on top, but if that's not possible and you want to keep this aspect ration, a darker gradient from the bottom will give the image a nice base.
