I think your main issue is your tendency to draw over the same line multiple times. Your lines end up looking scratchy and difficult to interpret.

on what you're doing well, the shoulder and hip lines you draw are pretty good, keep with that, it can be pretty helpful. You also did a very good job on capturing pose and proportions, demonstrating a pretty good understanding of the human body. Once again, you just need to be more confident with your lines!
