I like the texture of the garlic skin and the overall tone of the image.
I would have used a bit more DOF to get both heads in focus, crop a bit wider to get them complete and look for a simlpe background (of the same tones).
Agree with the above. A bit of each is in focus, if this was intentional then well done. Peronsally i would have one in focus and use the DOF to background the other
