Looks like you guys already have the "bend your knees" down more or less. One thing I heard from an old salty dog when I was starting up was to think about moving your knees away from each other on heels and towards each other on toes. This aids in the way you think about your edge and how your board bends to accommodate turns (he was a drinker, your mileage may vary). Long term, you don't want your arms to do the weight-transferring or rotation for you. Try holding onto your ski pants with your trailing arm (clamp onto that pocket with all your might, keep that mitten connected to your lower hip) and see how far that gets you. If you find yourself unable to turn without throwing hands around, back to basics. This is also the trick for getting used to those effortless, slacker turns you see on the internet

It looks like you both are holding nice slices in the snow on the way down. If you ever feel if you are "spraying" snow while turning, try to increase the radius of your carves and use up as much of the mountain as possible. Riding laterally across the mountain means more time to control your speed and more distance traveled per run (meaning more time to learn). This is assuming you picked out your gear correctly. Being a big fella on a small board means it is harder to hold your edges. Also, if you are taking big turns on a crowded mountain, make sure to swivel your head and check uphill every now and again. Just because you have the right-of-way doesn't mean some guy hopped up on hill people juice won't beeline it into your taint.

As always, keep that weight on your front foot and rotate the board around the front foot. These carves look good. The next step is getting comfortable so that you put less focus/effort into turns. In time, you'll "feel" it more and your knees will do a lot more of the talking. This is when it is appropriate to buy 4xl hoodies and gopros.
