This is an interesting idea. I would have left out the kiss in the extreme foreground out of the picture - as it stands it is distracting. I think the light should also be a tad dark and increase the tones.
I was expecting spattered circles of molten chocolate while waiting for this to load. Lost points because Kisses are overdone and lost points because Kisses are really crummy chocolate.
Gained points for seriously good control of focus and DOF.
This composition seems off... the front left kiss being out of focus hurts it I think because it is the most predominate subject in the composition, yet, just a bit out of focus. Although, I understand you were going for the circle on the base of the kiss... - 6 - JeB
