You might want to try doing some lunges as well as this will improve your ability to balance and withstand pressuring the front of the ski.

under videos then wintersports for some WC race clips, keeping in mind that these guys ski very aggressively and have stiff equipment (and ski in a tuck much of the time). The videos posted by catskills will probably be more helpful.Detail
: After thinking about it some more, I realize that I pull, or drive my inside hip quite a bit when doing turns, while focusing at the same time on my outside ski edge. So if I were turning to the right I would look in that direction (important) and leading with my head I would drive my body in that direction using my right hip, arm, and shoulder although the left arm should be forward as well. However most of the pressure will shift to your outside ski so your focus will shift to there while your body compresses at the apex of the turn, then it evens out until you are ready to change edges. Again, when I was first learning how to carve on skis (still kind of am) I would just stick my leg out and lean while letting my inside ski do what it needed to do, mainly just keeping it out of the way. Gradually I am learning to how to pressure the inside ski.
In simplest terms, it's kind of like flying but with more muscle involved. Seriously pretend you're superman
and start turning (I'm not kidding). The most important part is just to look where you are going, and the body will follow (even with skis attached).
I also learned a lot one day from following my dad's tracks (doing quick skidded turns - he learned on shaped skis but skis more old style).
