https://practicedrawingthis.com/3d-models-index/ having a really hard time with visual memory, some of these simpler forms were way easier to start out with!

So I tried just doing one page of boxes and went right into the project but immediately got overwhelmed, so back to the warm up I went! As I did 2 pages I started noticing what I needed to practice so I gave myself the task of doing 100 boxes. By the halfway point I felt a lot more comfortable with the exercise and then realized I still have to work on making my lines that go into the vanishing point straighter. On to the project now!
