Swell job on your sketches, Munkedragon, that's very nicest! Nicest because of the range of motion put in those sketches.
Again, if I was to suggest on what could and would be improved on, then it should be to check out this link here: https://line-of-action.com/learn-to-draw
Not to mention the fact that, would and could, you please do 79 more minutes of 30-second warm-up poses??
Why???? Because this link is especially for newbies here in this site, but that's not all, it'll help you and support you and your goal so much, that you will get a lot of the spirit of Freddie Moore, Legendary Disney Animator!
Hat's off to you, and I hope you'll find this completely and totally influential, supportive, and welcome.
30 seconds is very short, so you need to relax, but it's better to express the joint with a little bit of strength. Or if you practice with a darker line in the front of the overlapping parts, I think it will help you get more formative.
