I wouldn't guess the tree is the main subject like it seems hinted by the focus. Look is touching even though tones at eye seem to be pretty blocked. So the contrast is not where it should be.
Nice crisp image. Great range of values. The fact that your subject is slightly in the shadow and the focus is a little softer complements his hesitant expression. You made a connection with your subject that the viewer can feel. I would crop this closer. The subject's highly lit clearly focused left shoulder distracts from the really powerful elements in this photo. Nice job.
Cute. The focus might be off a bit. I know how frustrating that can be. It wouldn't be so bad, you could have said you did it for that soft focus look, but that darn tree is right there in front. I do have a suggestion though. When you want to focus on the boy and he is cooperating, move him a bit away from anything that might grab the camera's attention. On this one you could have had him step a foot away, prefocused on him and then have him step back to the tree. He would have to be in the mood to do that, but it might be something to think about.
