A nice fun image. I like the composition and the cropping in general. You have caught a good, natural moment. The white balance seems off though. Normal house lighting can be very tricks to get looking right in a photograph. The cameras Auto White balance usually gets it wrong and the incandescent setting is often a mile out too. I have found that the only way to get a good balance indoors is to use manually preset white balance if the camera supports it.
White balance is off along with the focus. However the child looks as if they are having fun and thats what counts. Technically, you need to make sure that have your white balance set correctly and in a picture such as this one you really want the focus to be spot on. I wish you well in this challenge and many more to come.
