Perspective -- Zorro's Cave

It's not of Zorro, I know, but remember from the old Disney show there was that one mine where his Native American allies were waiting for him to talk about...something which eludes me at the moment?

Anyway, this is for my Perspective class. It's supposed to be single point perspective of an interior. We were asked to choose one of four themes for our projects in class, and I chose Zorro: hence this.

Prismacolor col-erase pencils are the greatest things ever. Seriously, never going back to using normal graphite. This was put into grayscale in photoshop--I have to eventually add value to this. I'll upload it again when I have value AND color. WOO.
