Thanks for the feedback, guys. From your comments it seems that maybe you see what I was aiming for. I realize that hummingbirds are a pretty common (overdone?) photographic subject, and I (like many others) have shots that show them close-up and in detail. However my objective here was to concentrate less on the details of the bird, and capture instead a sense of its behavior by letting the motion show through. But even more important to me was its environment. I'm particularly fond of nuanced, out of focus backgrounds, and that sort of impressionism is why I picked this frame. Even so, it was important to get some detail in the bird's eye, without which the bird (and the whole picture) would seem unanchored.
