Taking black birds on white rocks will always present a problem. I feel there is loss of feather detail in the blacks. Also feel the image could be improved by cropping.On the right there is a beak intruding. Cropping out the 2 birds on the right would help.
Also on the left there is half a bird on the top left. This needs to disappear, either by cropping, even if you lose some of the tail of the lower bird, or by cloning, depending on the competition.
