Nice color on the bird itself but not a fan of white backgrounds normally, but you got the xposure of the bird correct despite the background.
Acute angle always a problem with these birds have preferred the tail be clear.
Im glad you can handhold a 400mm -I gave up a long time ago.
Chas.
I think Chas. covered it well. The waxwing has such soft coloration, that I do think they do better against a softer BG when available. Tail merge noted, as was shooting angle.
I might give him a little more room at the top and to left. I think adding to the top a bit might reduce the impression of shooting up so much.
Hope to see more!
Thanks very much for your comments, Charles and Randy - The compositional comments are particularly helpful to me. I was actually torn with which cedar waxwing image to post - here's the other one. If I was about 20 feet tall it would really help :)
I personally think the waxwing would have benefitted from some fill-flash, or some more EC (I know the 40D does not go higher than +2 in AV or TV, but you can push it more with manual - this would also have given you a "truer" high-key image). Good to see you posting again...hope to see some more :-)
