I'd like to see the bird with more blue sky to the right (crop the left and extend the right) and I would probably clone out the smaller twigs (especially the hot one) and just leave the main perch.
The colors look a fair bit over saturated and I do see some noise.
Good points by Jim. Placing the bird more to the right would help the composition. It does have the look of a heavy-ish crop. I would probably remove the lower smaller catchlight. Beautiful individual here, nicely fluffed up - and it looks like you had good light.
