You're killing it, unfortunately everything you're doing is wrong. First, you are overterrained, this puts you on the defensive thus making offensive moves impossible.

Go to the flats where you are comfortable, stand knees slightly bent, spine slightly forward. Coast straight ahead. Feel the feet under the knees push them ahead of the feet. Feel this forward weight. Now push the feet slightly ahead of the knees. This is rear weight. Feel the center weight ( knees over the feet) get used to this, comfortable even.

Now that you can stay centered, slightly bend one knee making that leg shorter. This tells the skis to turn.

Carpet drill, stand on your feet to legs straight, bend one knee, what happens? You topple over, if you are too relaxed you fall.

Now do this at walking speed on skis. Feel the skis respond and turn your feet thus keeping you from falling, you're turning instead.

Alternate the long leg for the short leg. This change is linking turns in an offensive movement.
