I'm in a similar situation, i'm gonna study animation later this year(3d animation and drawing), and i like drawing, but my drawings suck, and they don't suck as hard as the stuff i made 4 years ago.
I guess this depends on where he wants to study, but college is supposed to teach you how to get good, my mother studied art(engraving specifically), and she had been drawing since she was little, so she didn't have a hard time, but she had some classmates who sucked, and they got better after some time at the school
Also, has he ever taken art classes?, i consider myself a pretty bad artist, but having teachers helps a lot.
If he's only done about 6 or 7 drawings, it's natural he sucks, drawing is hard, you can't get good that quick, you need to practice.5) He doesn't even have Facebook. He is too shy to interact with people even online. As of right now, his portfolio consists of about 6 or 7 drawings that he has put so much time and effort into, but as I said, are nothing special.
