First of all, you've been playing jk2 for at least more than a month :P. How can you call joorself a noob? It's not like you get pounded in every single duel?
One "Artistic move" or rather three is the Crane Jump/Lounge jump. Quickly tap
Forward or Strafe then hold jump, and it'll make your character model perform a special jump that isn't really all that strategically advantageous but it looks cool with saber ignited.
Wall Flips and WallRuns: Strafe in the direction of the wall and hit jump. For wall runs, hold yourself at an angle towards the wall: Forward+ The direction of the wall and press jump. If you tap jump again you do a premature graceful leap off your wall run.
There's also the weird forward-backward roll, in which you start a forward roll then hold Backpedal, literally making your character do half a roll. Good for pissing people off in the start of a duel, who like their "space"
