The green is overwhelming and white in the box ends up looking greenish itself because of everything around it. The presentation is fairly plain and stolid. In judging this challenge I don't ask "Does this photo make me want to eat this?" I ask "Would I want to hang this on my wall?" This might work as an ad but not as a work of art. There's extra unused space around the image, particularly at the bottom, so it could be cropped tighter.
I like the concept, but think the color balance could go a little less green. It is very challenging to remove color cast when there is so much green reflective light, but maybe introducing some more red somewhere in the image might have made it easier to balance.
This is a tough challenge to vote. I'm torn between "what are you trying to do here" and "what do I expect here". Further complicating matters is the question "what would I do here".
What I would expect would be a technically strong piece of eye-candy that would present the dessert in a way that I would want to at least sample it, if not order it. Along these lines I'm looking at technicals: backgrounds, distracting elements, exposure, sharpness. I'm also looking for creativity, imagination, and originality, which can make up for less than perfect technicals.
So, where does this leave me with your image?
I'll give you points for technicals, but the image doesn't do much for me.
Heh, love the humor introduced in the title that is demonstrated in the photo:-) Lighting is good on the subject and you have some good detail. The critique is that the elements just sitting amoung the backdrop does not tempt the viewer to want to reach out and grab the handful. While the green backdrop is close to matching the hue of the text 'Junior Mints' it does little else for the composition. It needs that little extra 'touch' that would make it very appealing to the eye. The green is too neutral a tone - perhaps a warmer tone backdrop would allow the candy to shine or even introducing an 'location experience' (the candy sitting on a table with bokeh background of what is clearly a movie concession stand in the backdrop).
