TS - Desert Cube

Desert Cube - Pencil, Ink Pen, Marker

I've been reading a great book (Comic? [Graphic Novel?]) called Perspective for comic book artists by David Chelsea. I always had a firm grasp of geometry and perspective but some of the methods for constructing shapes that are accurately set in perspective are fascinating. I knew of one, two and three point perspective and understood the idea of convergence and foreshortening but I never really knew how work with all these accurately. So far I've always just taken a guess based on what looked right. Well... no more of that, now that I know how to do it properly.
