I like the red sky, etc., which gives the picture a nice effect, but I don't like that the red "spilled over" to the bird. The bird also has a red tint to it. If you could isolate the bird, keeping it pure black or some other color that contrasts well with the red, it would be a lot better. IMHO. :)
i love this shot...and i really like that the red tint is on the bird, too. i think it really gives the feeling of the bird being enveloped in the surroundings....much more than if the bird were just silhouetted.
Really, I think it would look good either way. If I were to do it though I would isolate the bird, but that's just me. Either way, it's a might fine shot!
