Looking for a new approach

Hi yall! I’m looking for a new way to approach learning anatomy. So far I’ve been tracing over photos and recreating the tracing using my own observations. The results look fine imo, but I think theres a stiffness? Or maybe they look a bit unrealistic? Advice on new methods and critique welcome.

Hi there!! Your understanding of anatomy is really strong because of this method! All the figures look realistic to a human body.
Usually, what helps me with stiff forms is doing 1 minute gestural drawings. It forces you to focus on the overall form rather than the anatomical elements. Doing sessions of a handful of 1 minute drawings might be a good method to try out!
