The lighting at the end of that white tray (?) is a problem, maybe more contrast would help; otherwise a very pleasing image. You've got me heading for the kitchen.
A very well thought out title ;)
I like the diffused lighting in this, but I feel that the arrangement could have been more interesting by using perhaps a wooden cutting board for some nice texture and colour and maybe some care with placement of the sandwich so it would have sharper focus and interest and a bit more interesting pieces of fruitty bits.
I can see a depth of field issue in this photo. Since it's static, you should have used a great f-number to have more depth of field. The part of the breat close to use is not clear, then the image is not sharp. Lack of light also. But the idea is clever, the tree cumcumber could have been aligned some how with the bread to have another triangle.
