Well, if you are going to have a bigger perch, you might as well have an interesting one, and this one is.
I might tone down the brightness a bit so it doesn't out compete the bird.
Your bird is sharp, nice angle in frame and good composition. There is a little noise in the darker areas of the background, not too noticeable.
I would suggesto that you give the whole thing another round of USM, still, great pose, lovely light, BG, nice perch, detail and exppsure! Congratulations!
