30 minute figures

I find the 30 seconds very dynamic!

your work is so clean and it looks amazing! my advice for reducing stiffness would be to exaggerate lines on purpose. i can see you're figuring out the poses by using lines and circles for the limbs and joints- try to break free of that! try to see shapes in negative space and focus on the interesting curves and flow of specific poses rather than using the same line method for every single drawing- that may be a source of the stiffness. hope that helps a little, keep up the amazing work
