If anyone knows of a book that dumbs down this subject and actually makes it understandable for the mathematically challenged, I'd greatly appreciate any suggestions 🙏

Very much enjoying myself. I used to draw portraits and it was neverending stress having to perfectly capture a likeness. Trees are much more forgiving 😊

Thank you! This is my first time drawing in five years, and my first time drawing from life instead of a photograph, in almost twenty 😳
