contest/jam

You sound intermediate level

Anything but the lowest class

Don't think of it as competeing, focus more on landing all your stuff. Act as if nobody gives a shit what you're doing. (Because really, nobody there really gives a shit) You give the most shit, so just land everything and RELAX.

How old?

Go party at the jam man

With the tricks you've listed, i'd say intermediate.
But if it's you're first time competing, i'd say beginner.

Join a lot of contests and don't join to win, join to have fun.
You'll get used to having eyeballs looking at you.

Just don't be a dick and go the lowest class if your better then that , nobody likes a sandbagger

3rd Lair contest?

How was it?

And to answer the question, do what you are confident in, and just tell yourself you get the park to yourself for a minute or two. Ignore the outside folks. Just go have fun.
