I don't think his jawline's "overstated."
Argh, there are just GREAT caricatures!...They remind me of the character designs in "Gargoyles."
I can't say too much more, except that I REALLY like these, and wish I could do profiles with as much conviction as you do!

Cute drawing. :) I take it that it's a self portrait of you and a friend. While the guy's jawline is a bit overstated, as a whole the picture is very well laid out. And like I said, cute. :D
