This would be perfect if the background were the dock at Key West! Arrangement is OK and perspective fine. Might be better if there were more color from things such as tropical fruits surrounding it.
The lighting is a bit weak which makes the white plate too grey. The pie looks nice (the back of it could have been included and in focus) but there is a lack of contrast within the pic as a whole.
Good focus. Lighting seems flat and doesn't do anything to enhance the shot. Perhaps an additional light off to one side could give more depth by providing some shadows for more interest.
The focus seems a bit off, and the empty space at the bottom appears to serve no purpose. I like the inclusion of the fork, though, and the pie looks good. :D
