really helpful technique ^ once you know how to divide by halves and thirds it makes drawing evenly spaced things in perspective waaay easier:
I too dyscalculic for this type of shit 😭😭
it's honestly a lot simpler than it looks, you're just connecting corners and drawing lines where they intersect. I really recommend you just grab a scrap piece of paper and try it and i'm certain it'll click! It's one of those things that makes more sense when you try it yourself.
The perspective examples I showed above look complicated, but the underlying technique is very simple. You just keep splitting the rectangle until it's divided up evenly as many times as you need it to be.
The stairs were split in half multiple times to divide it into 8, the cell door was divided into thirds and then those thirds were split in half to give 6 lines.
