Its an interesting shot. Detail looks excellent. Pose is perfect and the eye is sharp.
Colors seem appropriately subdued and are pleasing.
To me the main question is the crop. A bit unusual as a square crop (which I like) and the bird is a bit more centered than I would generally do. But you have interesting framing with a series of triangles formed by the branches, echoing the triangle formed by his legs. And he seems to be sitting in a neat little house outlined by the angular branches above. All in all, this makes for an unusual but interesting composition. It keeps me looking returning to the image, discovering a bit more.
I dont know how you got here, and if there are other variations that work. In an ideal world I'd have the bird a bit more to the right, a bit less of the busy branches on the far left, and still try to do the square crop and triangles. But these are nits.
