Some notes on the movement Wave Hands like Clouds. Generally the head and torso move together rather than the head leading. In a form head torso and hand are all fixed together, but I imagine outside of that you want your head moving first so you can see what your blocking/whatever. Feel like you kinda got lazy with the (character's) right arm compared to the left arm. Left does a smooth scoop then follows through, whereas right just drops and weakly goes through a similar motion.
I see. Well this is only the first iteration. Maybe I'll increase or reduce the sway and see what works.
