It looks great! If you’re really wanting feedback, just going off this latest drawing, it seems like the feet and hands (but especially the feet) are areas where you could improve. My advice
for you to take or leave, haha is to gather some reference pictures of hands (either online, Pinterest is usually my go to online source for images, or offline, you could take your own reference pictures with your phone or tablet if you have one) and select a number of hands/feet or pages of hands/feet you feel you can commit to, and then going off your references try to learn what you can whilst copying them. 🙂
if you’re not at all in the habit of doing practice like this id suggest a lower/more doable self-set goal.
