An interesting take on the Mockingbird, Dave. I like the pose and its obvious attention and displeasure with something over there. The black and white treatment is interesting and the colored eye works, though it’s hard to say if it is an improvement over the original color.
There’s something going on with the plumage that doesn’t look quite right, possibly the large crop coming into effect and excess sharpening to try to compensate. There is a distinct sharpening fringe along the top of the head and the back.
