I like the selective color - it helps to focus the viewer on the flamingo even thought the position of the bird isn't so compelling (with its back to us) There is some odd green left in the bushes/grass inthe back and yellow in the water wich is distracting. Rotating counter clockwise would look better.
Nice selective Desaturation, the only thing that kills this shot for me is the green hose at the top, IMO you should have cloned it out o cropped it to make the shot better.
