Technique looks pretty solid. Clean lines and logical proportions. Shapes suggest movement though could have more fluidity and freedom.
The strongest point that I can see holding you back is timidity. Your good don’t be nervous or constricted. Let there be a more natural discovery of the form instead of a strict dictation of it. Your lines are also very light it appears in this photo, I suggest you use a softer lead or press a little harder, hardly any shadows are visible in these, it looks to be almost entirely line work and a bit of mid tone, you need more values. Don’t underestimate the significance of shadow and highlight, arguably the two are more important than even the mid tones. Even if your aim is a more illustrative approach focusing mostly on the lines, use some method to represent both shadow and highlight through line work if you must, or avoiding values/shading intentionally.
your shapes are otherwise beautiful and for 8-10min poses you did well in your representation, it’s obvious you didn’t allow yourself to get caught up in single areas of detail like the face but treated the form as a whole. You spaced things out well and have a consistent vision that makes your style look cohesive. It’s my opinion that if you were able to incorporate bold and intentional shadows and highlights to where you are now, that your work would leap forward substantially. You’re ahead in so many other ways that I think it would unlock compositional thinking for you as you’d feel adequate in your ability to craft the figure.
