Welcome to Epic!
At my resort we would put you in a level 4 lesson group because you are linking wedge christie turns (starting turns with your ski tips closer together and finsihing with your skis parallel) on moderate terrain. At this level we work on things like getting rid of the wedge, getting the skis on their new edges above the fall line, getting more speed control through turn shape and less from skidding, balancing against the outside ski at higher speeds and using the poles to help our turns. At 3-5 days per year it is possible to move beyond this level of skiing, but you have to make a commitment to do so (e.g. inline skating in the summer, 1/2 day of lessons and at least 1/2 day of practice/drills each season).
One drill I would recommend for you is carved traverses. Stop on one side of a trail and aim your skis at a point on the other side of the trail. Head straight to that point and then gently start tipping your skis to the up hill side. Your skis should turn uphill until you come to a stop and leave pencil thin tracks in the snow. Start slow, then pick points farther down the trail to increase the speed. When you can do this after starting going straight down the hill, you are ready to start working on turn transitions.
