Surprisingly, I improved a lot in that area yesterday! I'm attributing it to the advice from
@François Pugh to tip the ski more though the turn. I was able to go slow (like really slow) with a lot of turns down a groomed black. Usually, I accelerate more and more because my turns are not short enough to dump the speed... Tipping skiis to a bigger angle was an eye opener - thank you! It made it so much easier to make more turns in the same space (on groomers).
I agree tipping the skis more will help, but that's only partially what needs to happen. As your skis go flat during edge to edge transition, you are far too impatient to turn, and pivot the skis to get the turn going. If you want to learn to carve, that's going to come primarily from edge angle and ski pressure. Have someone show you outrigger turns, and develop a feel for dialing back the flat ski pivot instinct right out of your turn. You also need to develop a much stronger and balanced outside leg.
Committing to a bump to make a turn on does not always work... I chicken out and make a turn on the next one (or the second one... or the third one...)
Because you are not skiing over your feet. Because you cannot complete a turn and be ready for the next turn
before you complete the current turn. Because your current cycle is turn, recover, shop. Turn, recover, shop. Your cycle needs to become TURN, TUR, TUR, UR, UR. That's right, some turns should be missing part of the beginning and the end of what you currently do. This is building on what Francis said, "Make more turns in the same space." Get thee to a light blue slope and make your turns sharper and shorter and quicker until you can turn
faster than once per second. "Oh, but that's hard", I hear you saying. "It's difficult to get the skis to turn that rapidly." Yes. You have to ask them, they won't do it by themselves. Turn with vigor, with strong intent. It takes skiing in an energetic fashion, while staying over [the center of] your feet.
Lastly, remember bump skiing is more than skiing on a surface that resembles cookies on a baking sheet. If you just turn (rapidly enough) around the cookies, you stay on a flat surface. Hey, this is not so hard! This occurs sometimes with fresh snow on a firm base. But it doesn't stay that way. As the bumps get skied in, the surface transitions from a cookie sheet to an egg crate. Every path choice has 3D undulations and implications and forces to throw you off balance. That's a talk for another day - For now, work on stance and turn rate.
So much to discuss in this one photo:
Look at how far behind your feet your hips are.
Look at how the angle of your calf does not match the angle of your back.
Look at how you are not strong on the downhill leg - you are in no position here to be able to lift/lighten the uphill leg, and that is a big problem, going on instinct here, but I'd bet a beer that is causing several cascading problems and limitations.
