Yes, there are some very good pictures there. Agree with other comments. Try dialling in a little + exposure compensation. Also, if you're close enough, you could try using flash in FP mode to get better face illumination in daylight. If your g'friends son is any distance away, it might be too far for flash.

I think you have a good eye for photography. There is feeling in your pictures and those who can convey this always make more interesting photographers.
