The placement of the orange makes the composition very interesting. The picture size almost makes this look like a pumpkin. I like the lighting, kind of gives you a feeling of the way that the moon is lit."10"
heavily saturated colour - to the extent that in the brightest area of the fruit it's begun to lose detail, and yet the overall image isn't very bright at all. The idea is good, and the execution not far off, but perhaps brightening the whole thing and then reducing the saturation to bring back those details would help graduate the light across the skin? Still, a good illustration of the smooth/shiny and pitted feel of orange skin.
Overall I think it's a well executed shot. Presumably you are trying to communicate the texture of the orange, but the lighting and composition promotes the orange itself insteaf ot it's texture -- to me that is. Yes, texture is present unfortunately not enough to captivate me. Good luck.
