The lighting is way too harsh for my taste - using flash well is very difficult, especially up close. Personally I would have preferred a white background as well.
You showed texture pretty well, but for some reason this just doesn't look appetizing at all. I guess this close in it just makes it look a little dirty or something, I'm not sure. Good macro, though; your focus is good.
Excellent macro. Nice natural color and the contrast of the red and green is really good. The light creates a few bright spots, but overall, really nice.
