Camera Work/Technical: Nice capture and very nice focus. I also see some sort of color hue as well. I think that your post-processing is the culprit here.
Lighting: Excellent use of natural lighting. His face is lit terrifically and nothing is lost in shadows or blown highlights.
Composition/Content: I echo the adoration of previous commenters in that the expression is priceless. I do think that your cropping is just a bit tight. It give the image a very crowded and cramped feeling to it.
My Opinion: I like it, and I think it fits the challenge nicely. With a bit looser crop and less the hue, you score would have surely grown.
I like what you had in mind here. He looks like he just got caught sneaking candy before dinner. But, there seems to be a green cast to the image or something else is a miss... kudos on the image but i'll have to take away some for the editing.
I know that wet candy canes can be sticky, but I'm not understanding how this photo is resembling that. I would have liked to see it messy either on his face or hand. Funny facial expression though, really is a cute kid! Nice photo, just maybe not right for this particular challenge.
