Yellow Headed Caracara

This is the most work I've ever done in photoshop on a photograph I've taken! I loved the shot, but since the bird was very close to the bars, they were very evident across its body, which, due to its proximity, couldn't be helped much when taking the original photo, and I wanted to try to rectify that problem (keeping the original, of course) to get a better photograph, since it was posing so nicely for me! While this is far from perfect, I'm very pleased with my efforts, and hope to improve the technique with time!
Mainly using the dodge tool (which lightens pixels), burn tool (which darkens pixels), colour replacement tool (to match feather colours) and clone tool (for the background)

Feedback would be very much appreciated, and original is here: [link]
