Here are some other spins you could work on kasanya:
Reverse Chair
Chair with one leg extended (not sure of the name of this one)
Forward Falling Spin
Backward Falling Spin
Front Hook Extended (where you bring your outside leg out and around to meet your inside leg)
Cradle Split (Cradle with your legs in a V)
Just some suggestions…
P.S. Sorry if the names are inaccurate!
