10-Second Lighter and Scribbler Action Sketching Warm-Up

Done as part of a practice session with poses of 10 seconds in length.

My current goal is: Develop my own signature drawing style (advanced)

I'm just so obsessed with getting my lines of action, lines of rhythm and gestures going for my drawings and doodles and sketches. What do you really think of this? What can I do to really, really take this one up a notch??
