Some nice moves going on there. Good steering movement of the inside ski and of the CM across the skis into the turn.
To pick some things to work on, I'd start with making sure the CM moves forward into the new turn, not just across the skis laterally. In the top right photo, the lower legs are pretty vertical, and your mass got pretty far back. By the picture on the bottom left, it doesn't seem to be a cronic problem, but something that happens once in a while. You can also notice the tip of the inside ski is in the air, but the tail is on the ground. This is another clue that your weight got back. One thing that I notice that does seem to be consistant, is that, while your inside ski steers nicely through the turn, the edge angle isn't complimenting the outside ski. Notice how your knees are always together, but your feet are apart (A-Frame)? This means your inside ski is not edged as much, and if you were to put any more pressure on it, it will get very skiddish, and be hard to control. An exercize I learned, that works on this, is to tie a piece of string, patrol tape, or caution tape (anything can can be broken, so that you don't get hurt) around your knees, loose enough that you can get your knees about 6-8 inches apart. Try to ski without letting it fall down to your boots. One other, minor, thing that I see, is that you ski with your hands very low (below your waist). This will tend to hunch you over. I'm wondering if this wasn't caused by being a bit tense in front of a camera. But otherwise, your hands stay very nicely out front.
All in all, some very nice skiing. Not a lot of wasted or counter productive movements.
