the great artist … Cool course Many thanks!

Nicely done! They look very good. One tip for the woman with her hand on the ground, though, is that with especially arched poses like hers one side will curve as it stretches, which you captured nicely especially in the first one, and the opposite side will squash/crunch together. This opposite side is an opportunity to emphasize a sharper rhythm, as the separate directions coming from the hips and the upper torso cross at the bend. Having one side more straight while the other curves also lends itself to an interesting rhythm and balance across the figure.
