The bird, perch, and BG look good. There is good detail in the blacks and the whites. I would remove the leaf on the left. And I might add some canvas up top.
Good details and eye contact. I also would clone out the leaf on the left and try to get more details in the shadows. I agree regarding a bit more canvas at the top.
I like the colors, sharpness, and head angle. I would clone the leaf as well as the branch stub that appears to touch the base of the bird's tail. Well done.
