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.
