Yes.
It is.
One thing I would really try to watch out for is the dreaded "front hand swing". That's when shortly after starting a heelside carve, your front hand swings across the nose of the board and ends up somewhere over your front foot toe. For regulars, this is your hand swinging from left to right.
This is one of two bad things. 1, it can be a subconscious effort on your part to wrench the board around with rotary momentum. Or 2, it can be the result of unbalanced rotary momentum in your body (board turns left, upper body doesn't, upper body has to "catch up").
Concentrate on turning as one unit with your board. Don't fight the equipment. Let it do what it is built to do.
Furthermore, isolate one skill at a time and work on just that for a number of runs or even a whole day. And do it on a slope easy enough that you don't have to be too concerned about speed control. You can't learn in self-defense mode.
