Wow. You're taking this seriously, aren't you? Okay, here is my first drill for you.
1. Raise your right hand over your head.
2. Bend your right elbow so that your hand rests between your shoulder blades.
3. Move your right hand in a fore and aft motion repeatedly so that your hand touches between your shoulder blades repeatedly
There you go. You just gave yourself a pat on the back. You have most certainly earned it!
The differences between the two videos are significant. What I saw in the first video was a skier with a loose, undisciplined upper body that was dominating what his feet were doing at many times in the turn. Now, I'm seeing a skier with a calm, quiet upper body, who is turning from the hip joint, and using his feet to manipulate the skis. Great job! Your hands are right where they should be, the pole touch is in the correct ballpark, your shoulders appear squared to the mountain for the majority of your turn. I also notice some increased edge angle, which has eliminated the 'floppiness' the feet through the turn.
Now, to take it to the next level, here is what I would like to draw your attention to. In the POV shots, you did a good job of giving an angle that allows for good MA, we can see your ski tips. And what I'm seeing there is that you have a slight stem when you initiate turns. When you make a left turn, it is not always there, and sometimes so small as to be unnoticeable. However, when you initiate a right turn, it is almost always there, and more significant. This tells me a couple things. First, you are still a little hesitant about committing to the fall line and letting your edges go to initiate the new turn. Second, it tells me that you are right leg dominant, and more comfortable turning to the left, when the right leg is the outside leg.
So, to work on that, I would suggest doing some sideslipping. I would really suggest you do it on a steep pitch. Like really steep. 40 plus degrees. Now, I'm not suggesting you find a gnarly double black to practice this on. Find little spots where the is maybe 20 or 30 feet of steepness. The sides of berms, etc. Always make sure you have somebody with you to watch for people coming, because these little steep bits are usually blind from above. get on that little drop, and sideslip down it, slowly. Stop and start in 5-7 foot increments. What you are trying to focus on with this is the simultaneous edge release. With a steeper slope, the feedback is going to be immediate. If you're leaving your uphill ski behind, it is because you aren't releasing both edges. Practice this until you really get the feel for both edges letting go at the same time. Once you have the feel for that, take that into your turn. As you start each turn, you want to feel that simultaneous edge release you practiced in side slipping.
That being said, you have definitely shown us a breakthrough, and you are doing a great job! Keep up the awesome work, love the enthusiasm and desire to learn! *high five*
