This was a quick (20minute), joint effort manip from me and my son. He doesn't do much artwork and rarely uses the computer, but he showed a little interest so I did my best to coach him and show him what little I know... He's only 10, so we stayed away from the nudes...
10 years old and better than a lot of the stuff I have seen out there. Of course... there is cnstructive crit... but we will wait until he is at that age where they are allowed to compete in school. But yeah... not bad for a kid.
Good for you in involving your son. I had my daughter playing on a pc at age 3, she just loved the old windows 3.1 version of Paintbrush or whatever it was called. She can use Photoshop these days like a pro, which I can't because I'm stupid.
