1. This needs more light; you've got bright light coming from image left with the subject looking right, leaving him (her?) with a bad case of raccoon eyes and under-exposed skin. The easiest thing to do would have been to use a reflector to bring some of that light on to the face. Even better would have been an OCF, off of the subject's left shoulder. Some of the empty space above could be cropped away, it adds nothing, and I think too that the image would have been stronger had the child been looking more toward the camera.
2. This one isn't bad at all. Again, a reflector would have helped illuminate the whole eye socket and provide a nice catch-light, but it's not too bad as-is. The main thing would be to have lesss empty space above the child's head and more below.
Just my $00.02 worth - your mileage may vary.
