Don't know what made me remember about this, but a few years back, I was invited to a show called Spare Time Gallery; the whole idea was to show what artists at dayjobs did on the side, and as I had just started IRON CROWN ... it fit.
(I also didn't have essentially any collection of original works - sometimes you just have to wing it like that.)
I'm not a very public artist (to put it mildly); so having my first official gallery was both as terrifying as it was exciting (ironically, despite tabling at much larger conventions a few times before. What gives?). Went great, of course - meeting a bunch of my coworkers and us all letting our hair down by nerding over 3D printing models and on was the way to go. I'd gladly do something like this again.
