Nice idea. Well lit, and the choice of center composition was the right one. The one thing I don't like is at the top of the opening, there is a pretty big gap between the zipper and the rind.
A very very cool idea - well executed and the lighting's great!
The only nit I have is with the reflection being neither here nor there. I would've either put the entire reflection in the picture or would've taken out most of what's visible now and kept the orange almost at the bottom of the pic. But that's just a nit - something that occurred to me after spending a lot of time enjoying the pic.
