It's still early and I wasn't hungry...then I looked at your picture and thought "hmm, that looks delicious" good exposure and the light isn't harsh. I'd say good job. But, if you are looking to amp up your food photography you should check out Nicole Young, she's written a book on food photography and her portfolio looks great.
