Lovely and intriguing shift from still and focused body to blurry background via moving wings. It's like you added a third layer, made of movement, between the subject in the foreground and the background.I definitely love this shot.
I definitely tried to get in a position with a more pleasing background so that the hummingbird was backlit. A little soft on the head and beak however in my opinion. A little faster SS would have sharpened it a tad more, but im pretty happy with it.
