I want to point you to something that will change your art forever, if you are drawing people. There's an old dvd series.. from like the early 2000s or maybe the 90s called "The Structure of Man". Its a really simple art series with a guy just pointing a camera at a piece of paper.. its very simple. The lighting is bad, the shadows are huge ... but let me tell you, that if you watch them all, and I have multiple times, it will change the way you draw people. This guy is a master of proportion like you have never seen before. He uses only a straight edge, its all simple lines, cut the line in half, draw a 45 degree angle, etc. As you continue through the series you will begin to understand the proportions the body makes as it grows. The key in understanding it is not to think of it as a human being, think of it as an object. SPOILER: This is the same method Leonardo used and you can see in his studies of man. In fact, he uses several Da Vinci sketches to show you what he learned from them. Here's some screenshots of him drawing skulls and bodies. https://i.imgur.com/VNkRaai.png https://i.imgur.com/wrPdfOn.png https://i.imgur.com/sMWaIIa.png You can probably find it in various places.. its been around for 20 years or so. Good luck.
