If you've ever skied and felt wooden its usually because you're trying to assume a fixed position. I bet you lack in energy and struggle to 'perform'.
Try to feel the undulations in the Mountain terrain and go with it. Forget about standing in such and such a way...
Be natural and active...
Be natural - Don't lock yourself 'forward'.
Move vertically - Use your range.
Be sensitive to the terrain.
If you want to really master the sport of skiing then go and practice. Getting in the miles is important, I can't stress that enough.
Best wishes,
Martin
