This was fascinating. I hadn’t done this type of drawing before and I found I would start in the upper left hand and work my way clockwise. When I looked down I would find that the upper half from the 11 o’clock to the 3 o’clock would be fairly ok but the the 4 o’clock to 10 o’clock would be way more distorted, larger, and tilted down such that my lines never even got close to meeting. I am gonna call it a night but I wonder if I tried to do the same thing but started counterclockwise drawing from the 2 o’clock position if it would have similar warping or opposite warping. So cool!
