Great shot. I might have cropped it a little less tightly, leaving a bit more of the background on the right and bottom; I feel it is cropped just a bit too close to the frogs leg in those areas.
I also personally feel this would benefit from a little post processing work (or a little more if you have already done some); mainly increasing the color saturation and sharpness levels. However there are purists who would say it should be left in a more "natural" state, so feel free to disagree.
