|Okay, you have donuts like this in your apartment or were they at work? If they are in your apartment I can help you with that dilemma, just hand them over and no one will get hurt! ;)
As for the shot, some tough comments, I honestly gave this a 4 during the challenge. And for most of the same reasons stated, dull background, slightly out of focus and rather uninteresting composition. This could be done and with a few changes be a much stronger contender.
First the background, go to white or black on shots like this. Give the camera a starting point for the white balance. Some people use posterboard but I prefer cloth, less glare if you have the right material. Second, the plate, the blue rim around the side is a bit distracting, again, a solid color plate, probably white or even a serving platter of some sort to give it an air of elegance.
The lighting seems a bit harsh, I'm thinking you used the flash or had harsh overhead lighting, a more diffused light with the camera on a tripod coming more from the front would have made a big difference in this shot. The set up the shot isn't bad at all, just the surrounding elements. Oh, do get rid of the wrapper with writing if you use cheese in another shot, it detracts and takes the focus away from the food and of course, get a chocolate donut! :)
