Use the "Phantom Move" to increase your tipping and angles.

Here are two movements you need with your inside foot, ski and leg. 

Small and simple movements with the correct body parts make efficient skiing.

 When the inside ski is light, off the snow,  like in these two photos, you can tip it easily.
Also notice how he hold that inside ski and ski boot back. Don't let that inside ski slide forward if you want a quicker turn.

Here you can see the effect of tipping. The inside ski base is visible and his body moved to the inside of the turn, the outside ski is angled and pressured.
