Okay, so I had a cartooning jag back in February and made several strips featuring "Brain" or its goa'uld version, "Bra'ain".
This is the strip linked to this icon:
I think this is undoubtedly an illustration from my fic "In a Strange Land" where Dief and Fraser are shape-shifted tentacle-aliens as per Galaxy Quest (it's a crossover). Fraser and Dief communicate telepathically and Dief's extremely disreputable, unlike Fraser, who's desperately trying to pass as human. In the icon, Dief's doubtless getting his end away with a local poodle behind the bakery, to Fraser's dismay. And yes, I do still promise to write the sequel, in which there is Ray+Fraser+tentacles :)
It makes me think of the beach, that he's surfing - the end of the day so the light's golden towards sunset, and his beard's heavy. But it also looks ominous, post-apocalyptic. So maybe he's surfing at the end of the world, because what else can you do?
I made this for the AO3, because you can only have one icon and a fandom-specific, even a writing-specific one didn't work. So this is for fic and art, both. It's the 3 primary colours and the 3 secondary colours, just an abstract design that looked good. I used to use the "Mandelbrot's Ass" one but then he died and it seemed kind of disrespectful. *eyeroll* Like he cares.
