What a beautiful bird! I like the pose, the perch (I love the moss on it), and the colour of the BG. I agree with Mike about toning down the bright spot on the bill - and to a lesser degree on the legs/feet too. I would also even out the faint vertical streaks in the BG above the tail. Excellent colours throughout, and oh so sharp.
In addition to what has been said about the spot on beak and bg I believe that because this one seems to be exposed to the left a bit that I would try a bit of play to make it pop some more.
Maybe slight vibrance and levels adjustments.
Quite nice Alexander, love the detail and colours, I would agree with Daniel regarding the vertical stripes and with Kim regarding the levels adjustment.
This is very well executed Alexander. Lovely, looks almost like a set-up in a studio with an added background. It is really appealing to me. I would perhaps lighten the eye a little and crop above the head by a third. I love the pose and the plumage is immaculate. Did you use a hide?
Stunning! Lovely colours, BG and exposure. Just feel it needs a tad more space, and also another vote here for the removal of the stripes above the tail.
