@LiquidFeet and others already laid out a good plan for you to start with so I won't suggest anything else except one small pearl wisdom: It's in the Hands as much as the feet!.
While in the bumps, ( and this includes your practice drills ) if you can't see both of your hands in your field of vision facing downhill, you are on the road to ruin. When on the groomers practicing your short bushed carve turns, practice quick wrist flick pole touches that are timed with your turns.
Oh, and edited to add: If you make it your mission to succeed in the bumps, you will. And, the rest of your skiing will improve ten fold.
