The angles on the perch draw you to the bird. Colors are nicely rendered and I like the light. Looks as if his bill has some really bright areas. Wish it was posted larger as I can't really get a bead on the eye.
What a gorgeous capture. Love the textures of the perch and what a lovely BG. I would crop just up to the first break in the perch from the right and maybe work on the eye just a tad. Just love the pose, the colors and the details. Truly stunning capture.
