Yes! Appropriately enough just this week, I had to make a trailer for my Kickstarter Campaign! Here it is:
I ultimately went with a very silly approach. I wanted to be clear that the comic does have progressive and feminist themes, but in a way that didn't come across too "worthy" sounding and put people off, so I wrote out a trailer where I kind of play the butt of the joke (since my voice sounds so fussy and proper it really works for that, especially with the angle of me being known online for voicing a fussy, proper character). Part of the inspiration was the trailer for Hearthstone Wizard Duels, so I asked my VO group, Voxus, if anyone did a really good "Obnoxious Monster Truck Announcer Voice" and Trevor Wilson is like "Yes. I can do that." and oh man, he delivered!
I've also made a video on instragram in the past, which wasn't hugely effective, maybe because it moves a bit fast, or maybe because it focuses on the action aspects rather than the characters and comedy?
