FWIW, Your skiing is progressing but the same timidity in the ski/snow interaction is present.
My suggestion would be to do exercises to elicit more one legged skiing to improve balancing movements and enlarge your movement pool window. This in conjunction with increasing the engagement of your edge angle and your shovel at initiation.
Static: Simply standing on the side of the slope notice how your weight is distributed between your feet. Now lift the poles and your up hill ski and remain in balance. What do you have to do? Notice how your head must move over that down hill foot. Now, set the uphill ski on the snow but remain standing with predominant weight on the downhill ski with your head over it.
Traverse: Now practice shallow traverses on a comfortable pitch while balancing on the inside edge of downhill ski and notice what is required to maintain that balance and not set the uphill ski down at all. (tip: keep the ankle flexed to aid this balancing) Note: a barometer of where your weight is distributed fore/aft is your uphill ski and if it is dangling level, tip up, or tip down.
Garlands: Do the above in progressively steeper traverse angles. You should find that a bit more momentum makes balancing on the edge easier.
This will require you to counterbalance more with the torso creating more angulation in your body and flexing the ankle a bit more to aid balance. (if this is overly difficult some adjustments to your fore/aft alignment may be in order). Once you have done a few of these to either side and feel a strong edge engagement (no skidding) it is time to progress to engaging the shovel more by thinking of pressing the toe piece down into the snow as you balance on the edge of the downhill ski. You should discover a better ability to change the turn shape by changing the fore/aft pressure along your foot. Remember, in order to remain balance over the outside ski you will have to move more over it with your head and shoulders than you may feel possible, intially. This exercise can then be progressed to the point where the committment to the outside ski is occurring before the fall line and you are able to balance all the way around the turn on just the outside ski.
This exercise may be difficult for you to do right now because it pinpoints an area where you are lacking a movement pool to move within but with practice your confidence will grow and your turns will become more dynamic and your edge angles much higher. Create the platform and trust it to balance along. Once these movements are ingrained, the inside ski can be feathered back into the turns but the angulation felt in the onelegged turns should be retained and worked in to your movement pool repitoire. As long as you remain very two footed biased you will never feel the other extreme of the spectrum which is exactly where I think you need to visit and hang out for awhile. Take it to extremes by seeing how high of an edge angle you can achieve and remain in balance. How far can you get the hips inside the turns? Get on some carving skis or slalom skis to really get'm out there.
I could be wrong because many times I am?
