nice work!
i think you should focus on shape
in 1 min just draw the landmark anatomy like head, spine, leg, and hand + line perspective, dont forget the contour line
in 10 minutes dont to focus in face. add a silhouete to make more 3d.
Keep it up!
In my opinion, 30s-1m is for expressing idea inside your brain. So just draw what inside your brain and put it in your draw, dont thinking that gonna be bad or something.
Try to remember and focus in landmark of face, dont to much focusing on detail. Just let the viewer know if that was eye, nose, mouth, etc.
That's all i can say. Good work!
