Laughing kids

Dreamstime has another contest - this time the subject matter is about body language - I just finished this rough using a wacom tablet and drawing in Adobe Photoshop:

I drew the one boy with the front teeth missing, but I'm not going to do that in the final drawing.  Because it looks dumb.

This is the cleaned up version.  I did it in Adobe Illustrator. I rounded out the blond boy's cheek (it was a little too stylized) and removed the gap teeth.
