Good idea, but I think I'd have tried a fake background (sky, scenery) to emphasize it, or else ceneter the image vertically and emphasize the repreated interlock effect, like a gear on edge, a running yin/yang symbol, or a positive/negative look.
Very simple, but an effective shot. Love the sort of "double negative space" thing that you have going on. Color, focus, composition and concept all great.
Very sharp photo. Good detail and color. May I assume "lero" is part of a larger name (that I have no idea what that would be). It doesn't move me or even make me hungry for chocolate (can't really say why, it just doesn't). Hugely minor nit: several fingerprints barely visible in the chocolate. 7 Rob the Swash
