Ok here ill try my best.
1. It kinda seems as if he was crying just a moment before. Not seeming to happy I'm not sure if thats what you where going for.
2. Super Super cute! But lighting is as good as you had so it turned out as a super great pic with meh lighting.
3. Adorable, looks almost as if someone said his name and he thought he was in trouble and was about to say something like.. UHH-O (def. My fav.)
