You have a very expressive line and that is nice, but i feel like you are lacking in structure and understanding of volume
i recommand you watching and trying to follow some videos about gesture drawing like
or
or if you can spend money i highly recommand brent eviston's gesture drawing course on udemy, there are sales often and it's really cheap especially considering the quality of it.
i also feel like your shading technique is a bit messy and i think you should learn what i said above first with no shading, i think learning structure first will make you understand crosshatching better, then you can add shading, i promise it'll be easier!
i see a lot of potential in you, if you work on these just for one or 2 weeks your drawings will look amazing i'm sure you can do it :)
Very good figures, your proportions are pretty good but i noticed your lines are a bit wonky and they all have the same line weight. i recommand using a stabiliser or working on your line work by doing an exercize that consists of drawing 10min of circles, 10 min of straight lines etc, and also using a brush with transfer where you can have variation of line. line weight is a great part of figure drawing and can make a piece come together and it makes the figures more readable and you should know which parts of the body to emphasize with a strong line and which parts to imply with a subtle line. also remember to draw using your shoulder not the wrist for more free lines. But it's overall very good you have a great sense of volume good job! cheers
