something like this right?

I rarely in the water (maybe once a year), I will continue practice with the surf skate drills...

Thanks for the advice, so my hands should be parallel with the rail & left elbow should be on top of the front foot (doing that will automatically square up my shoulders)?

Does the feet needs to be close to 90 deg on the center of the board because that's my Bali coach keeps telling me to do so the board is centered.
