Well the wrinkled background is really distracting which would have been taken care of if this really was a shallow DOF shot. But I'm sure you've heard this a million times by now.
Other than that I find the maroon cloth very distracting, perhaps take it out or find a matching color. The crop is really tight at the top for me with too much space at the bottom.
Good idea for a still life however the forground subject is too close to the backdrop producing a background that is not quite out of focus enough. The wrinkles on the backdrop are quite distracting.
