My advice is to state the limitations to successful shooting in your first post so the viewers are aware of what you know and are coping with - so comments can start there and you'll hear things you don't know.
As it stands this is a cute kid with a deer-in-the-headlights stare but the picture is not worth posting for comment on a photo site because all the negatives points were out of your control.
Sometimes a picture can't be made with the equipment and experience available.
Learn to recognize those occasions and learn to work with an off-camera flash, bracket and diffuser and you will avoid the almost red-eye, the pinpoint cache lights, the blown out skin texture and the under-chin shadows in this picture.
