I would acquire an artist manekin and draw it on different interesting poses. This will help you translate a 3d world to 2d surface. Once you can draw very simple figures in a variety of poses that look good, then you can start adding more details and experimenting with line weights. In art school, you start drawing from real life models to understand these fundamentals.if you have a local college they might have a figure drawing night for the community. That's worth checking out imo! https://www.amazon.com/Artists-Mannequin-Blockhead-Articulated-Decoration/dp/B085H9J2VY
