I think they're fairly decent. But I do notice a lot of repeating lines. Maybe try making a single stroke to show motion instead of doing multiple? Overall you've captured the flow of the poses very well!

First congrats for starting to draw again! What i first can see is that you try to find the contours with too many lines at a time. I also still have problems with scratchy lines and have to be really patient while drawing. -try to use less lines, or practice to build up the lines on top of each other instead of next to each other - maybe warm up with some more beans before drawing figures and rewatch how proko is drawing. Hes planning every single stroke really well and sometimes you can see him ghosting the lines in the air befor he puts the pencil on the paper - you should check out his latest free videos on YT about drawing basics and line quality. I think you can benifit from it ! keep going and be patient with yourself. You will see that your lines will get better with regular practice. I swear.
