IMHO some really nice skiing overall. I like what you're doing with your upper body. It's more upright, you're not "hinged" at the hip joint. I especially like what you are doing with your head. Believe it or not, your creating an angle with your head. At times skiers lean their head in towards the inside of the turn which can mess with your equilibrium causing balance issues and it further leads to banking into the turn. So, Great job !!!
Sorry about the quality of the screen shots I grabbed. I'm not a tech wizard. Looking at the first photo, and I understand that these are just moments in time. Clearly, you have built some really nice angles using the ankle and knee joints. The ankles, knees, hips, shoulders and head all line up quite nicely as you can see. You've created a solid platform to balance against without pushing the skis out away from you, you're standing on the outside ski, and your hips are inside the turn as a result of building that balance platform using the ankle and knee joints. This happens as a result of continuing to flex those 2 joints after the apex of the turn. I didn't mention the hip joint because it is my opinion that you are using just the right amount of hip flexion to accomplish your intent, so don't add movement or try to fix what isn't broke. Continuing to discuss the second half of your turn... as you continue to flex the ankles and knees, you are still maintaining shin contact with the fronts of your boots. What you should feel is your weight more on the heels. This doesn't mean you are in the back seat. Since it is the bottom half of the turn, the weight needs to be back in order to control the back half of the skis and finish the turn. This deflects the skis across the slope, leaves you with some stored energy to start the next turn in a forward position. This is very much a timing thing. When you start to relax, lighten or release the pressure from your outside ski, this creates instability, which allows gravity to take over. Your COM will cross your skis and you will begin to topple down the mountain and into the next turn. If timed correctly, your skis will start to shoot out away from you, leaving you in a forward position where you will have control over the front half of your skis (shovels), your hips will already be inside the turn, and all you really have to do is wait for your new edges to "hook up." From there, as stated earlier, you should be focusing on flexing those joints to absorb energy and build that stable platform to balance against as the turn progresses. In case I'm not being clear enough, you can even PRACTICE getting as low, low, low as you can go to exaggerate the movement pattern using those ankles and knees. Clearly, you have demonstrated that you are capable and have the mobility to execute a really nice turn. Now for the elephant in the room... the second photo. I'm not going to harp too much about what you're doing. I just explain a couple things that are happening which will hopefully bring you back around to focusing on the ankles and knees. If you look at your outside ski and the arrow I've drawn, it appears you are "pushing" the ski out away from you. This has the result of "pushing" your hips inside the turn as denoted by the arrow at your hips. The inside ski is relatively inactive at this point and results in an A frame. As you can see, nothing really lines up and you have to add weird body movements in order to stay balanced against the outside ski. It also appears your COM lines up more on your inside ski. I think you can see the contrast between the 2 photos, so enough said on that score. Again, really nice skiing and speed management. Best of luck to you and thanks for sharing your video !!!
