I like it. However, because you asked for C&C, and because animal photography is so tricky, here's one thing: the focus looks ever so slightly off. It's hard to tell exactly where, but the bird feels very slightly defocused. This may be a result of some noise from ISO 800.
However, I think it's a good bird shot -- and getting the focus tack-sharp on animals is really tricky!
pretty good but seems a bit washed out. try bumping the contrast a bit.
i import into canon profesional (supplied software), edit basic in that, then if i need to do anything serious, i process in GIMP.Ecas32, what photo editor are you using? What is your workflow? How do you edit your photos?
