Good idea and a good backdrop setup. Would have been good to avoid the reflection of the lights in the cup, and perhaps a lower exposure as the orange rind looks hot.
This is humorous, which can be good. The inside of the orange is a little too bright, but the reflections on the glass seem minimum, although it also seems a little tilted. I'm not sure if you were going for the browned apple look, but I know they can do that after a while and usually lemon juice can help it stop browning up as quick if you werent. There are a few white specks on the background too, but in the 'normal' world those would have been easy to clean up with spot editing. It's not technically the best, but the unusual subject makes it stand out more.
