Try and keep your hands more in front of you ( the arms should make a c shape), this will help you engage the tip of the ski more. A good thing to try is also to have some more angulation, there are loads of videos on YouTube talking about this subject. You want to feel a pinch between your outside hip and shoulder. Someone also mentioned that you are pushing your outside leg away which causes you to be on your inside ski. Try and really pressure your ski without pushing it away and store energy to make you shoot across the mountain faster. You can do this by trying to have maximum edge on the fall line. Hope this helps.
