This evening's pencil workout was some instrumental perspective practice. I got confused super easily earlier on in the task. with all the crazy pencil lines/wireframes, I sometimes lost track of what it was I was going to draw. Anyways, it was fun, and I learned some things about uphill vanishing points. my next practice session will include some projected shadows!
Oh, and I also learned that I need a G-D yard stick or T-Square. I was using crazy shit as straight edges between the vanishing points.
