Zombie's Book of Sketches

[ZombieChinchilla]

Sooo I’m posting here again after a few months bc I’m struggling!! I want to do an illustration inside a greenhouse, but man I’m getting convinced that perspective isn’t real. The first two are sketches I did, based on a ref, the first one with one pt perspective and the second using 2 point. I’m doing these in Procreate on my iPad, and I’m using draw assistance for both. But they’re were looking off, so I decided to find some refs to study from, and y’all...the lines don’t line up at all. I’m getting multiple cross points and I don’t understand. Can anyone help? Any helpful tutorials/books to look up? I know I need to start but the basics, but...it’s not matching up for me. Thanks so much in advance
