Normally I would consider all those branches far too distracting, but because of this challenge I think it works great as camoflage. Nice blurred background Colors all work excellent together Good Luck "8"
I think I would have cropped the sparrow over to the left. Looks like the autofocus might have grabbed the branch above his head and left him a little soft.
This picture suits the challenge very well. I like the cold dreary look of it. The composition might be better if the bird was on one of the third. Also, if the focus on the bird were a bit sharper it would really add to your picture.
