@RLY I am on week 2 now with the OW, so take this with a grain of salt. main things I've noticed when comparing carving a snowboard...
On a snowboard your always on edge (mostly) so on a toeside turn you heels are higher then your toes, heel side carves your toes come up. the harder you carve, the more on edge you get. You also shift your weight more to your front foot. But on the OW, the board stays flat (parallel to the ground) so you have to adjust for that, keep your feet flat. Toeside turns should still feel very similar, but when doing a heel side, try forcing your toes and ball of your foot down, like your pointing your feet at the ground 10 feet away. This will help keep your feet flat and your heel side turn will feel more stable. It did for me at least.
I don't focus as much on front and back foot weight, but more like shifting my hips forward and backward. Not sure how to explain it, but it reminds me of surfing.
Another thing I noticed, if I push outward on both legs just a little, not enough to move my feet on the pads, stability increases on turns. If you feel the board wobble when carving, focus on pushing legs apart and the pressure may stabilize the wobble.
other than that, I usually ride snowboard/wakeboard in duck stance 15deg both bindings, but after carving on the OW for a bit, I notice my read foot has shifted to 0 or even +5 degrees, like alpine boarders.
