You finally made it through, congratulations! Your boxes look very nice and well-placed. Just a few quick notes:

  • A more variety of perspective and foreshortening (for example, dramatic foreshortening) will spice up your work and help avoid repetition. Plus, you don't have to apply the Y method to all the boxes. Other ways of drawing boxes are accepted.

  • You should definitely try doing bigger boxes (like 2/3 of the page long), as your boxes are uniformly small. Bigger boxes are much harder to execute, so practicing them is recommended.
