Replying to Advice on getting better at skiing?

Well I've been skiing for a while now, very casually. However this year I've been actually trying to get better. I can do very small jumps, and can ski backwards, and i'm wanting to get better. What should i be practicing freestyle-wise to get better? Or in other words what is the most beginner trick or freestyle thing that i can learn to start getting better. Any other tips on getting more comfortable with jumps or just skiing in general would be greatly appreciated. Thanks!
