The light seems harsh and there are some hot areas, also IMO itīs a bit oversharpened, but I love the comp, BG, detail and colors, the species is wonderfull. Congratualitons!
I agree with Ramon's assessment of this beautiful bird. A little work on the exposure in a RAW converter and a little less sharpening and you'll have a winner.
I agree with everyone ... but only up to a point. The thing I really like about this is that the glossiness really comes through and whatever adjustments you make should preserve that.
I agree about it being a bit to harsh in some areas but I would also try to bring out some detail in the darks of the neck. Aside from that it has a beautiful background and nice composition!
