I enjoy the color, however the angle of the piano is throwing me off. The problem is the edge of it takes you right to the end of the photo, some people enjoy this but in my experience it will take the viewer right off of the picture.
Also, I feel the flower is a bit too saturated. A very slight drop in saturation and increase of darkness to it would make it a middle point of saturation *meaning the piano keys are black and white, absolute dark and bright. Nothing in the "gray" range* Not really a fan of the selective color one myself, lately that has been getting more and more on my "do not do" list.
For the angle bring the camera down a bit as well, I feel like it is too high up.
