I'm not an artist, but I'm quite pleased with Skulder's room from my ongoing fic "Team Madrigog". Most of my other alien kids have been really bad about not exploring their rooms.

It's a long, narrow space with two "bedtubs" built into the wall, kind of like a two-tier bathtub. She sleeps in the top tub; her Guild master (the closest thing she has to a parent)used to sleep in the bottom one. There's a sinister poster of a temple, a flying saucer and [gasp!] a human, showing her fondness for conspiracy theories. The kitchenette counter is covered in cheap spy gadgets. She knows they're garbage, but they have sentimental value. There is also a pair of reading glasses which is actually her main computer. In the middle of the room is a coffee table piled high with fast-food containers from a nearby paella truck, and the place ain't exactly clean. All the clothes in the tiny built-in wardrobe are yellow, which in her culture is the colour of sadness. She's the local equivalent of a Goth.

If you go out one door you find yourself in a driver's cab; out the other door, you're on the rear deck. Her home is a tiny house-sleigh, currently tied to a radio mast on a near-featureless plain of ice. The roof is stacked with freeze-dried giant cockroaches which she feeds to Dasher and Prancer, her beloved twenty-foot-long velvet worms who pull the sleigh.
