Done as part of a practice session with poses of 30 seconds in length.
My current goal is: Reduce stiffness and make my drawings feel more dynamic, energetic, fluid
Admirable work, hello winter, but I've got one more small suggestion: I see some of the strong forms on some of the expresssions, why don't you 5 minutes of 150 second (2 minute 30 second) sketches, if you may please??? The reason why is because, your faces will become lesser in their stiffness, and more, and more feelng dyanmic, energetic, fluid, and vital. Hope that'll be totally and totally benign.
