Hi Sparky. First I'll describe what you're doing, then discuss it.
The start of your turns are strongly pivoted. The pivot takes you all the way to the falline before any significant pressure is developed, then a very skiddy end of the turn follows. Your upper body is pretty square to your skis through the transition, and the pivot is powered by a blocking pole plant, subtle upper body rotation, and foot twisting. You unweight your skis to allow the pivot to happen with a subtle up move. Your weight is slightly aft as you go through the bottom half of the turn.
If pivoting is your objective, then developing your upper/lower body separation skills will help you to eliminate the rotation and execute it more efficiently. It's called anticipation. Many drills can help you do that, such as hop drills,,, pivot slips,,, poles held in front facing down the falline,,, hands on hips keeping upper half facing downhill.
Learning to eliminate the up move and let the energy of the skis do the pre pivot unweighting work will require developing more energy in your turns. To do that you will need to learn to feather onto a cleaner edge immediately after your pivot, thus finishing the turn with less skid and more ski bend. This will result in more speed, and more pop out of your skis as you release during the transition. When done properly, the up move can be replaced by rebound and retraction.
For the fore/aft issue, just work on becoming acutely aware of where pressure is located at the base of your foot. You don't need to push down on your toes to get fore balanced. In fact, that can do just the opposite, by opening your ankle and pushing your calf into the back of your boot cuff. Instead learn how flexing your ankle and extending your knee is all you have to do to move pressure at the base of your foot fore and aft. Practice skiing in various states of fore/aft, using those joint flexions and extensions to manage what state you assume. Also practice moving from one state to another during the course of a single turn.
If pivoting is not the goal, and you want to do clean entry carving or steering, keeping a body square to skis stance as you are now will serve you well, but you're still going to have to get rid of the pivot. If that's a problem, let me know and I can provide some ideas on how to fix it. I can't tell for sure by watching your video if well refined arc to arc, or clean entry steering, is in your bag of tricks or not.
I've used quite a few technical terms in this post. If any left you wondering, have a wander through my glossary. It should explain most of what I've been talking about. http://www.yourskicoach.com/YourSkiCoach/Glossary.html
