Love the pose and light. Sharpness is good and the exposure is nicely controlled. The bird feels a little tight in the frame to me; I would add some canvas to the top, bottom, and right. There appears to be some cloning visible near the wing tip on the left side of the image.
Excellent! The pose and colours of this bird really take it to another level. I agree that the image would benefit from more room around the bird, and a bit more sharpening (for the web at least).
I do not usually use this tool in Photoshop but a spot on the sensor did not give me another chance. I did not notice the defect. Thanks for alerting me.
