Bundling the "bunny" question set.
18 - Where do you get the most inspiration for your art (aka "bunnies") from?
From stories or from prompts, sometimes art also happens because I want to try a technique I've seen. Sometimes discussions and non-fiction posts inspire me, though that happens more for my icons which I use in discussions.
19 - When you have bunnies, do you sit down and start making art right away, or do you write/sketch down the idea for further use?
It depends. If the bunny is for something quick and cracky that is very context and time dependent, like comment art, I just do a scribble. That doesn't happen all that often, but when it does I end up with things like
Tim turned into a lesbian centaur,
John and Rodney in Woody Allen sperm costumes, or
Batman getting a time out. For most fanart however it doesn't go like that, because the impetus to make something is less immediate. So I have a file for fanart ideas, write down my idea and most just land there to rot. I usually think about an idea for quite some time, and just imagine it in my head, and only start drawing if the idea is compelling enough and I keep liking it for some time.
20 - Do you ever get bunnied from other people's stories or art in the same fandom?
Yes, definitely. (Though bunny should not become a verb.) I like illustrating stories. Other fanart inspires me more in the sense that I sometimes want to try techniques.
