1 Minute figure/Gesture Drawing Critique

How can I improve?

these are great ! your poses are super clear and your proportions look accurate too ! maybe the only small thing i could suggest is in structure- although the shapes read clearly to suggest the human form, some longer studies on anatomy could help bring more depth n realism into your gestures. i personally find it helpful to look through musculature diagrams online while redlining models to help me further understand what im looking for while drawing .
hope this helps!
