The only advice I could give you is to pay attention to your foreshortening. Spending maybe a few sessions on construction drawing in perspective will be a great tool for your development. I see some small habits of not extending the arms enough or being unsure of the overall 3D shape of the limbs and maybe not having enough time to render the hands. It's key to see everything if you want to know if the proportions are correct.
Overall great drawings and I've learned a lot from having studied them, great work!
