I should have taken out stock in Hershey for this challenge! :) Fun idea, but I would have preferred to see it done in a more artistic or creative way. The composition could be improved, I think, but at least including all of the smileys (bottom ones are cut off), and I think the lighting here is very uneven and un appealing for the chocolate. It appears to me that there's an overall purplish cast to the photo
I think it needs better lighting? Kind of harsh in the center and the shadowfrom the wrapper is distracting. Also feel that the smilies could have been framed better.
Funny title and idea. I'd like to see all 4 smiles in the frame. A more even light would take away the hot spot from the wrapper and even out the colors on the background.
