literally just keep trying it. a higher rail and a bit more speed with help the rotations come around easier. I also like to watch the ski addiction videos. theyre short and sweet but can really help with little things you might not have considered.
Should I be trying to continue looking over my shoulder with the rotation?
I think this is it, I learned front 2s and I had to look over my continuing shoulder more to get the spin around cleaner. I got the same season goals as you, haven't started to work on the back 2 yet, good luck
not much wrong with that. positioning and timing is all good. now try playing with it at different speeds, getting lower on the rail, pulling your knees up in the air etc.
