We all know that the Cyan/Tavion style is a hell of a lot like Windu's, and the Purple/Desann one is a lot like Palpatines.
Therefore, I suggest Cyan/Tavion's pointing at target animation, which already looks a lot like Windu's style, needs to be tweaked a bit. Player should hold saber near head pointing ahead, with both hands. Elbows should be behind body and body turned sideways.
This is how it currently looks:
The stance needed is like
But the arms need to be drawn back and the body needs to be more sideways.
As for purple..just make it an overhead stance.
