I can throw in the rope, now what?

I bought a HL Broadcast and I've been out on it 3 times now. I feel like I have pretty good handle on surfing without the rope. I can throw it in almost immediately after getting up, ride up and down the wake, near and away from the boat, and even ride up to the swim platform and get back in the boat. What's next? I'm having fun now, but I know there is more to it than this.
