More backwards looking over outside shoulder, also trying to switch which side I am looking over backwards, and backwards two-foot slalom making sure to get both edges parallel and really commit to being over the skate. Most rec level skaters 2-foot slalom (including mine until recently) looks pretty half-hearted to me, with the inside foot (the one on an outside edge) not really following the other foot fully. Also straight line barrel roll to turn to backwards on one side is weaker than the other - I am not over the skate fully. Just never ending little things that are tiny adjustments but feel huge and make a huge different to how smooth and comfortable and confident one is.
