Composition is fine. It looks like you used a flash so it took some details out of the bird feathers. I like the gray tone of the bird but think the pink area around the beak would make these pop if it was brighter. The focus seeme a little soft. It might be fun if you played around with rotating the image to see what affect you get. IMHO
i like the capture and crop very much. the lack of lighting on the tail though kind of makes it fade into the background, which is something i'm not liking, as the rest of the subject is visible. great idea though, 6
