The waltz jump 3/26

Waltz jump I an edge jump. I start with my left foot forward and push off with my right foot. It's a half rotation in the air.when you push off you swing both arms back with my right leg, as I swing my arms and leg forward you step forward. The toe pick is the last part to leave the ice and at the peak I bring my arms into a bent across my chest position and land toe pick first into the ice and put my arms out and you must land on the outside edge

My problem: I over extend my right leg when doing the jump, I swing it around instead of going straight which is making it harder to jump and I'm turning too soon
