Hi,
These are nice photos, whether it's of Tommy or Mikey. Personally i can think of putting the second photo of Tommy on the left, and Mikey on the right with the main light source coming from the right in a painting, if i'd to do it. The slight overexposure becomes the advantage for you to differentiate the light values between the two boys.
And, not to mention you get to keep the puppet on his hands.
