I like your photo, however, I think it would have been an awesome photo if you cropped the tails in the top of the photo and cropped out the bottom row of birds.
this shot has tons of potential. I love the 5 red beeks in a row in the bottom right of the image. Gives me an idea to frequent the local petstore everynow and then.
Well done
Good DOF on this. IMHO, the closest bars are distracting. Could this shot have been taken through an open door to look like it was from inside the cage?
