I slightly higher point of view would have emphasized the Arabesque formed by the tops of the posts, which would be potentially very nice. It is at least a classic.
Selective color, yeah. It's not bad here, though, it has a point at the rest of the scene is credibly somewhat monochrome anyways.
I'd have the robin a little off center. Unfortunately if you trim the right, you lose part of the arabesque, and if you trim the left then the bird is looking "out of" the frame, which is not preferred.
Next time: higher point of view, frame a bit more to your right, and then wait until the bird is looking in that direction.
