Let me piggy back on Dan. I was typing nearly exactly what he said when my dog decided it was time for a walk. You don't say no to my Dog.
My concern was the wrapping of the lines. Anything over 3 is noticeable and over 5 starts to become dangerous. You need to start going outsides, not so much for the lines as for the muscle memory you are building up. You have to train your brain to accept upright and inverted exactly the same if you ever want to become competitive in stunt. From what I saw on the video, you are ready. However, from what I saw on your earlier video's trying an outside loop is not where you want to start. It should be the lazy 8 or what I thought was a super suggestion from Dan to give it some down at the top of a wingover. It is important for you to know that your plane will turn outside, and fly inverted just like it does upright. That is not a given until you try it.
If you are going to try the lazy 8, and I hope you do soon, do it for the first time on a day with a mild wind. One of the reasons we like it is that the plane does not slow down much which makes that 1/2 outside loop back to level easier for the plane. It also gives you a cushion, especially with a little wind, should the engine not want to run well inverted, or the tank is flawed. You won't know either for sure till you try it.
Good Luck - Keep us posted!
