It's been decades since I used it in a practical way, but "How to Draw Comics the Marvel Way" - https://www.amazon.com/How-Draw-Comics-Marvel-Way/dp/0671530771 https://www.amazon.com/How-Draw-Comics-Marvel-Way/dp/0671530... is a surprisingly great tutorial for learning. You can ignore the bits on dynamic drawing that are more geared for comics, but it will give you a lot of foundational knowledge of composition and observing. The chapter on perspective is still one of the best writings on the subject I've ever seen. Pair it with a good life drawing book.
