Nice idea. The lighting is a bit strange. The background has a blue/cyan tint. Did you use a neon lamp? I don't know what white balance you used but sometimes automatic fails badly and then it's necessary to adjust it in postprocessing. Also the focus seems to be on the part with the many limes. I would like it more with the focus on the lone lime or both. -stephan
Nice composition, though I think it might also look nice if the slices on the right were taken out and the slice on the left was the only slice among the limes, just a suggestion, good job!
