Common Kestrel Posing

Common Kestrel Posing

This is a photo I took a while ago. I noticed this beautiful male Common Kestrel standing on this bush and the brave bird actually allowed me to come pretty close. The lake and land behind make for some interesting background to the impressive bird.

What did I do right? I got close enough to get a lot of details - if you enlarge the photo you can notice just how much can be seen. I used a wide-open aperture (f/6.3, as open as my lens allows at this focal range) to get a shallow depth of field - only the kestrel and some parts of the bush are in focus. All the rest is blurred away. Furthermore, the background is interesting and colorful, and adds significant value to the photo.

What would I want to improve? I should have placed the kestrel off-center, more to the right. Although the centered composition does work in this image (which it usually doesn't), I think an off-center one could work even better. There's always the option of cropping this to get the off-center composition, but that would trim the background and I think it's interesting enough in this photo for me to not want to get rid of any of it.

What's your opinion? How would you take this photo?
