To be completely honest, from the video you seem to be a confident beginner. Nothing screams out "advanced rider" to me. You're horse was on the wrong lead, you didn't keep her in the canter, and your body wasn't super stable.
HOWEVER, there is nothing wrong with that at all. I'm not much farther along than you are but I am honest with myself. The worst thing would be for you to say you are an advanced rider and end up with a horse that is too much for you. It's no fun saying you're a beginner but it will be worth it when you find a horse you can get along with and learn on rather than fight the whole way.
