The B/W and composition work well. I would like to see more of the right wing and the BG looks a bit noisy. I'm not sure if it looks a bit soft or if this is due to postprocessing.

I, too like the looks of this....rather nostalgic. The minute I saw it I thought of Alfred Hitchcock's movie The Birds. One thing that might make this a little more unusual is if you colored in the eye....might be rather dramatic.
