Replying to Advice for learning how to freestyle ski

Hey all - I've been skiing for years now, but have been really getting into freestyle skking. I'm trying to learn some cool tricks starting with a 360 and cross, I have my own stuff and am able to 180 and and ski switch fine. Any advice for moving up and mastering come cooler tricks? Is there anything I can do when I'm not at the slopes? I have my own eqipment. Thanks, also I'm trying to lean to take off switch, but have trouble with the "pop" Any advice would be great, thanks!
