What's next on the snowboarding learning agenda?

Okay, I'm going snowboarding with a free lift ticket. I'm already linking S turns (carved on blues, skidded on blacks) and getting into glades. The problem is I can't afford lessons. so I'm looking around online on advancing on my own (since I guess it's the only way) so what do you learn after making wide carved turns on groomed terrain and quick turns in the trees? I'm not interested in the terrain park because my board is really stiff.
