Greetings Dusty!
The first thing that jumped out at me was the wide stance. But for bowlegged skiers this is a good adaptation. Alas, you already know what the first piece of advice is: get new boots and get your orthotics adjusted so that you can stand neutral on your skis without your feet being > shoulder width apart 1/2 the time.
Here's what I see: Some of your turns are parallel and some are wedge christies. You start your left turns with a little shoulder movement. You turn your feet to change direction then set the edge to slow down. You have a tiny bit of leg flex at the end of the turn and tiny bit of extend going into the new turn.
Here's what I want to see: All your turns are parallel. Let the skis turn you instead of you turning the skis. Control speed more with turn shape than with skidding against the edge. Learn to "go" instead of "slow".
Here's how we're going to do it:
Get the boots fixed
Narrow the stance from outside shoulder width to shoulder width
Do the tug of war drill
Do the fan traverse drill
Learn the movements for making these kinds of turns with big turns first, then go back to making the shorter turns that you are comfortable with.
There are many different roads you can take to higher performance skiing. You can pick and choose what you like from the different advise you're likely to get or you can find a coach you can work with on a regular basis. If you ski in the Catskills, I recommend a visit to Ron White.
Tug of War
You need a partner. Stand with your skis sideways across the hill with your partner directly below you. Take your poles off. Hold two poles together with both your hands at one end and have your partner hold the other ends (most experienced person holds the pointy ends facing them). Experiment with how much force it takes to pull you down the hill. Vary your stance width, the direction your shoulders and hips face, the height of your butt off the snow and the edge angle of the skis. You'll find that you have the most resistance with the hips and shoulders facing down the hill, the butt low to the snow and the edges on high angle. This is the position you want to get in doing the largest turns on the fan traverse.
Fan Traverse
Traverse across the hill at a shallow angle. Beware of crossing downhill traffic. As you pick up speed, tip your boots and knees into the hill. The skis should track uphill until you stop. Check your tracks. If they are not thin lines, you turned your feet. Start on a shallower traverser. Gradually increase the starting angle making one turn/traverse to an uphill stop. Keep increasing until you are starting straight downhill and still leaving thin tracks in the snow. Remember to get into the tug of war position as your speed increases. Notice how effortless it is to slow to a stop by going uphill.
