I don't believe this photo has been published in my blog yet, so it's a good time to do some critique :)

What do I like about this photo? The beautiful subject with the incredible colors. The diagonal composition, with the wire and the Kingfisher contrasting, is very powerful, with the sparkle in the eye (and on the beak) adding some interest. The background is interesting. I used an open aperture to create a shallow depth of field, so the Kingfisher is sharp but everything else is blurred out.

What would I want to improve? A natural branch would have been preferable to a wire, naturally...
