You have nice details in your bird, exposure looks good as does the sharpness. You have a nice solid background and a good angle on the bird with him looking a little toward you. I think I might like to see a little bit of room all around if you have it. He looks just a little bit squeezed in the frame for my taste.
Bird details very nice indeed, but yes, a little tight. If mine I would crop just below those leaf buds at the stem top, but needs a little adding to jleft and base.
