Thanks Mario! If it is inspiring other artists then it's serving its purpose :).
Here's the finished motion study. These can really give your mind a work out. I have to admit that drawing a motion with drapery seemed a bit daunting at first, but I reminded myself that the same principles of movement for the body also apply to the drapery. You just need to analyse how it's reacting to the energy of the movement and simplify it into forceful shapes to keep it fluid during the whole motion.
