Composition is OK with me but I might crop a little more off the right. Detail in the blacks is compromised by them being out of focus -- not much to do about that. It might be worth a comparison to darken the railing.
A tripod might have given you a little more sharpness here, and could allow a little more depth of field. Hand holding 600mm at that shutter speed is thin ice and a high ISO limits the resolving power even more.

The bird's breast is a little soft due to DOF limitations imposed by the focus on the bird's eye (which was good). Diane's crop suggestion is good, too. Another option is to crop a little tighter at the top and wider to the right, assuming you have room in the original file.
But Diane's tripod suggestion is gold. I know, tripods are a hassle. They're heavy and awkward and nobody enjoys carrying them but we do it because they pay for themselves in image quality.
Agood tripod used properly often makes the difference between a nice shot and a real winner. The best advice I can give you is to get the best tripod you can afford and use it, especially with that lens.
Cursing under your breath while you use it is allowed!
I knew the perch would be met with derision. I don't like it either. But I only see these guys in my yard and they're never in a tree, etc. When will they ever learn? :)
