Nice angling of the swirls so that they point in a diagonal across the frame. I agree with posthumous that the black background seems jarring, not quite right.
It looks like you're showing off your ability to cut an orange peel. The natural light is the best thing about it. At least that gives a hint of reality, like there might be a real person nearby who wants to eat that orange. Having a black background works against you, though, brings me back to the "showing off" idea. Showing off might work sometimes in a competition, but when it comes to creating something that actual people in the real world will care about, it won't do.
Interesting idea, I personally think the light is a little harsh, and the background is a bit distracting... but I think with a bit more time it could be really neat!
