Dear writer or artist! Thank you for offering to create a fanwork crossing over two of these sources. As long as you generally stick with things I like and avoid things I dislike, I will love your story or artwork even if it doesn't take on any of my prompts, which are only suggestions. I am Isis
Some general stuff about my tastes: For written works, explicit sex (slash, het, or femslash) is okay, non-explicit sex is okay, no sex is okay, but any sex should be in believable language for the source, and there should be more to the story than just PWP. If you choose to write a sex scene, I prefer those that focus on emotions and perceptions rather than on the mechanics of what goes where, and I am rather vanilla in my preferences where kink is concerned: mouths, hands, genitals, toys, all are fine, but I'm not into BSDM or bloodplay or watersports or anything that might get a special tag. Gen is a-okay with me too. For art, I prefer R-rated art to NC17-rated art, and I'm totally happy with lower-rated art.
I have made some prompts and suggestions, but feel free to take things in whatever direction you like and/or include characters I haven't mentioned. I like: historical/worldbuildy detail, scenery porn, non-explicitly-detailed sex, ghost stories, supernatural elements, what-if AUs, original characters. My favorite tropes are time travel, bodyswap, and afterlife stories, though I'm perfectly happy with an entirely canonical scenario. In general I'm not a fan of AU that completely changes the setting, but if you have a brilliant idea, go for it; I would prefer "interesting" to "mundane" AUs, e.g., in SPAAAACE yes, coffeeshop no. (Coffeeshop in SPAAAACE, okay!). Except as noted, I would like happy endings and no major character death (unless it's canonical and results in ghost-fic).
For fic, I generally prefer plot (as in, things happening; doesn't have to be elaborate or long – as contrasted with character studies), past tense (either first person or third person – I don't like second person), and lots of dialogue. But these are preferences, not hard DNWs, and if you have a brilliant idea that requires second person or present tense, go ahead. My only hard preferences are for conventional pronouns, capitalization, and punctuation.
For art, I am happier with AU than in fic. I am totally fine with simple portraits, though if you want to show characters interacting, I have a soft spot for art in which one character is doing something typical-but-alarming, and the other is rolling his or her eyes, or reacting with horror, or getting ready to douse them with a bucket of water, or whatever. I like line drawings as well as full color. Stylistically, I love interesting and experimental compositions, unusual perspectives, emphasis on textures such as hair and clothing, and scenery porn (Mountains! Trees! Cliffs with water crashing on them! Brooding ruins of an ancient castle!)( This is a placeholder and will be edited to add specific fandom likes and prompts. )
