I agree with Gabriel.
Head turns towards where you wanna go, shoulders follow then lower body. Then depending on where you stand on the board (forward or aft), the turn will be affected by it. More forward will be less effective. More aft, the board will be more responsive. But then comes the problem of speed and keeping it. You can see on many surfing movies that the surfer moves up and down the board. It's either up for favouring the the speed or aft for the turn...
There are so many surfing styles and techniques out there that it would take a book to dissect everything.
Now, I wouldn't be any good for kitesurfing though...
Practice, test what works best for you... Check out YouTube videos....
Wipe outs are part of the fun...
...and no worries we all learn something everyday, that!s the beauty of it.
