I thought it would be a shame if this idea died, because I think it's a cool one, so I threw together a drawing based on the "Gun" crossover. My sleep schedule blames you for not one, but TWO archive binges (although I had read Gunnerkrigg Court before), so I hope you like the result. Because there isn't much continuity in Gun Show, I took the visual and humor style from it and combined them with a character from Gunnerkrigg Court.
I don't know if I'm supposed to make the next suggestion, but I will just for the sake of keeping this moving. I'm taking an idea from Thurber's New Natural History: the next artist's challenge is to take a few random words and draw a creature that matches each word. Note that the creature doesn't have to be described by the word: for example, a "Tall" doesn't have to be tall. Just draw whatever your brain spits out first. I'll explain more if this explanation is confusing.
