Hey! For 30-second gesture drawings, don’t worry too much about details like facial expressions. The goal is to capture the flow and movement of the pose.
Try using long, loose lines instead of focusing on small parts. Also, practice doing 1–2 minute gestures first, then come back to 30 seconds.
I’ve been practicing similar exercises and found some simple guides and drawing ideas really helpful for improving speed and proportions.
