Duckie, in my opinion, you are not allowing yourself to "turn" enough in your Cartwheel Mount Handspring. Try to think about turning to where not only is your face directed at the pole, but so that your hips are facing the pole too. This should allow you to bring your hips in closer to the pole so that you will have more control while you are getting conditioned to this move, and should help to "straighten" out your Straight Edge.
For the Spinning Scorpio it’s important to swing your free leg out and around instead of throwing it over. This will generate momentum which will carry you through the move with a more natural-looking spin. Instead of bringing the leg over and then beginning the transition, include the leg swing as part of the move, so that all the movements involved look like a single movement.
