wax on, wax ... wait, too much, try this, start over

I've got this one instructor, for my Illustration class, who never lets up. He is one of the toughest teachers I've ever had, and he bugs me to no end. It seems like he is never satisfied with my work, no matter how hard I try.

Of course, in the end, I've ended up creating some of my best work in that class. So I guess he knows what he's doing. You could look at it that that's why I'm going to this school in the first place. He's an art master, and even though he's tough on me he's teaching me the way. He's like my Illustration Mr. Miyagi.

But sometimes I can't shake the feeling that I'm just paying exorbitant amounts of tuition money to have an old man ridicule my work, y'know?
