If you are a midwest skier and serious about improving, there are some things you should do.
1. Get a real carving ski, i.e. a one step down from race carving ski or citizen's racing ski as it is sometimes called, radius 13 m or less, waist width under 70 mm (not a midfat that carves well).
2. Start tipping those skis onto their edges, and balancing along the outside edge.
3. Aim to make shorter radius turns and carve them with no sideways slipping, with more force by tipping the skis further, Do so by tipping the skis and retracting the inside leg while balancing along the outside ski.
4. Learn to flex that outside leg to release one turn and let your momentum move you into the next turn.
5. If you find yourself going too fast for the ski to carve a clean turn, stop and start over again. Eventually you will be able to keep you speed under 40 mph just by turn shape and how far you carry your turn up the hill. Do not push the SL skis past 40 mph; learn how they work at 10 to 35 mph and keep them in their sweet spot.
Eventually you will be booting out. You can tell this is happening by seeing where your boot toe drags in your tracks. When this happens be aware of changing surfaces; ice won't let you do that (ouch!).
A series of turns on a 300' hill is no different than a series of turns on a 2000' hill, except you can make more in a row on the bigger hill.
If you want to take it to the bumps, your are half way there, learn how to make those same turns with a little less edge angle so that you can do short radius turns that are not leaving thin grooves in the snow, but killing speed instead. Then take it into the bumps and make those same turns while moving your feet up and down to erase the terrain elevation differences. It really is easier at first if you go over the bumps instead of trying to go around them, but keep making those turns and keep absorbing terrain by lifting your feet as you go over a bump and shoving the tips down the back sides of the bumps.
A few drills to build upper and lower body separation and flexing won't hurt, but you don't need to do them all day long, maybe 5% of your day.
That's my opinion. You are welcome to disagree.
EDIT: Linked high angle turns is an attainable goal, you just need to know what to do to get there.
