Perspective

I spent a lot of time trying to get the shapes down (and the proportions) for this first one, but I didn't have a good idea of how using a horizon line and a vanishing point would help improve both of these.

In particular, it was difficult to convince myself that the shapes could follow the transversals (it seemed like they were too steep)

Kevin helped me with an example, which helped me see how I was supposed to /use/ the transversals to help guide the drawing. 

This second try was a little better. I feel a lot more comfortable with getting the right proportions now. I feel that with enough time, I could make a solid representation of the hall.
