I like your composition; the position of a second burger provides for an appropriate background with your shallow depth of field, and the lettuce in the corner improves the contrast of the bun of the subject burger.
The lighting is nice and rich, though I feel it added a bit too strong highlights on the right side of the meat of the burger.
The burger itself has some wonderful volume and brings plenty of colour to the photograph. The subject has a good, crisp, focus.
My originality score is perhaps a bit low, but I guess it's hard to bring some originality to food photography.
All in all it's a lovely photograph that instantly grabbed my attention above all the other food photographs in my deviations notification list.
