An issue with drawings is they can look kind of sparse, so you have to have a background. Originally this had a background that was painful to look at, and it was a nice sort of art challenge, of do you dare try to look at the drawing with those stripes of green that are very difficult to look at? But I wasn’t entirely on board. So I went back to the (ha!) and came up with this nicer colorful shadings.
Another issue (mentioned before) is the alt-text issue.
But sparseness, you either keep drawing until it’s so full (which also impacts alt-text), or you try to find some kind of balance.
