He likes his cheese! But he also seems to feel guilty about stuffing his mouth with it, if his eyes are anything to go by . Light treatment is strange for a children's portrait, I think, makes his skin look coarse, but you have made your choice for a reason, I suppose...
nice finally. i hate pictures of kids everyone with kids posts the exact same photos, and their not intesting to look at no matter how cute the kids are. but this is unique, interesting and fun. thanks for posting.
