Lesson 1 - The Basics, Part 1 from /r/ArtFundementals

I have completed Lesson 1: The Basic Mechanics of Drawing: Lines, Ellipses, and Boxes! It doesn't sound like a lot, but, here we are. Make sure to click through all the pages in each slideshow. The last ones tend to be a decent amount better than the first.

Lines: (2 pages of superimposing lines exercise, 1 page of ghosting lines exercise, and 2 pages of planes exercise)

Next, Ellipses: (2 pages of tables of ellipses, 2 pages of ellipses in planes, 1 page of funnels)

Next, and last: BOXES (2 pages of plotted 2 point perspective,  2 pages of rough perspective, 2 pages of organic perspective) Man oh man did this take forEVER

Now, I understand that this isn't some great amazing artwork. This is a way for me to keep track of progress and hopefully someone gets some useful exercises out of it as well. 
Here's a link to the lesson: http://drawabox.com/lesson/1

Happy drawing everyone!

EDIT: My sloppiness has been caught and I am properly ashamed of myself. Here is another page of rough perspective. This had me tearing at my hair and banging my head on the desk. Maybe I need a few more years of practice before I can draw straight lines.
