Hey!! I love those sketchy lines you do!
As a viewer, the quicker poses are a bit difficult for me to understand but that might be because the photo quality.
Technically, so,e of the proportions may be slightly off— particularly the head. It is a bit big. Also, although they are beautiful, I think it’s important to fully draw the body including hands and feet before any shading takes place. But I get it, drawing hands seriously sucks.
Anyways I think you’re doing really great so far and I can’t wait to see where you’ll go :)
