Exercise 3 on page 15 of How To Draw by Scott Robertson. I've never really done any perspective drawing before this. I think some of them turned out pretty good but some not as much. Hopefully I'll get it better figured out as I work through the book!
Damn good first go, better than my first attempt by a long shot.
One thing I don't know at all is about rules for placing the perspective lines. For these I just drew 4 kind of random lines then used those as guides for drawing the boxes.
