These are a good start. This is my first time being on proko and these are my first comments. I used to watch his videos almost 15 years ago when I was teaching my students because he would sometimes explain something in just the way that I was struggling to explain myself. Firstly, you are doing many things really well. You are seeing the motion and gesture of the figure/mannequin and you are achieving a very nice natural sense of proportion. This is excellent because it is often proportion that many people struggle with. In some places you can look to find a better description of how the structure of the form sits in front of another form. I wonder if you are drawing these from life or from some other reference. Also, there are places, for example in the third drawing, where you are describing the hands where you have indicated planes for the body of the hand and fingers but have not given them a thickness. To think of all of the forms as basic, three dimensional shapes, simplified will help you. In the second page drawing of the figure twisting, the pelvis could be a box drawn for us in three dimensions, even if we only see a small portion of it. I have tried to work over your drawing a bit to give you an idea of what I am talking about. The last thing I will say is that you are doing the right thing. Practicing. Keep your mind open to see where things work, and where they can improve. Just keep drawing. Nothing is wrong, or bad, only can be seen differently, with more form or structure. Keep it up!
