Even though this is an .avi file, real player and windows media will not recognize the video. Use this link
to download the divx player. On the plus side, the installation is fairly painless and the picture is bigger and good quality. On the minus side, it's awfully hard to freeze at specific frames.
Tell the camera person to use the zoom next time, eh?
You've got great rhythm and speed countrol. You're getting onto the new edge above the fall line during turn initiation. From the looks of at least one of the turns, you can carve out the bottom of the turn just fine. These skills will let you comfortably and confidently ski the whole mountain.
Where we'd go to take your skiing to the next level is to get more angulation instead of inclination and round out the upper part of the turns more. One of the keys to getting this is to either get more hip movement involved in turn initiation (as opposed to moving the entire upper body as a unit) or getting the skis to steer more out from underneath the body at turn completion. What this does is get the skis on edge earlier in the turn and build greater edge angles.
At the end of your right turn at 10 seconds, the skis are at a 45 degree angle to the fall line and flat on the snow. We'd like to see your skis at a greater angle to the fall line (i.e. more across the slope). At the frame I froze at, you can see your left arm starting the pole swing for the next turn, but starting from behind the body (editors note - this is real hard to stop and see this at this point, but you can clearly see the hands getting behind the hips at other points in the video). The shoulder is closer to the new turn than the hips are. If you get your hips closer to the new turn at this point it will help get the skis on edge quicker. Keeping your hands more in front makes it easier for the pole swing to pull the hips instead of pulling the shoulder. From the hips closer position, it's easier to get the legs out from underneath the body and get the body parts above the waist more vertical instead of leaning into the turn (see the points in the turn that are directly in the fall line and 9 and 11 seconds).
The easiest symptom to spot is the larger spray of snow below the fall line. At 9 seconds, on the right turn, you can see very little snow coming off the skis until after the fall line, when the spray goes about 15 feet from the ski tracks. Because you are not getting on edge earlier in the turn, you must set your edges hard, skid and spray snow at this point in order to control speed. In your case the amount of skidding is fairly small, but the spray of the snow betrays you.
If you can round out your turns a little more and get more angulation, you'll get more "zip" in your everyday turns and you'll find that you have better control in snow conditions that are not quite as ideal as shown in the video.
