I am a painting newb at best.  I signed up for a number of the speed painting events. Should I be concerned there will be nothing but super great painters painting?  I basically signed because it was 2$ and I got a mini and some time to paint.

There is some amazing painting that happens in the speed painting events, and then there are people like me who sign up for the same reasons as you. That, plus a place to sit for an hour.lol. You’ll be fine.
