Additional Likes and Dislikes (Important Note: your artist or author is not required to take these additional preferences about setting, era, tone, etc. into account, but it might help them come up with ideas, so include as many as you like. This is not the space for hard and fast triggers or squicks; those should be placed in the list of elements that you are unwilling to receive above.)
Likes: Ambiguity and complexity are my catnip, so feel free to explore regrets, heartaches, and desperate modes of survival as well as autumnal recoveries, rebuilt lives, buried desires, last or second chances, forgiveness, and fresh starts. Secrets carried too long, burdens laid down, families found or rescued. Misfits who are brilliant at getting on with it, leopards who change their spots. Backstories, long perspectives, human fragility. I'm not particularly sentimental, but I do root for romance, so you can go for poignant or joyful or both. Beauty in the shadow of death. I also don't mind infidelity. But please don't assume you have to write angst. Write whatever strikes your fancy, short of the unbelievably saccharine. Cross-gen and teacher/student dynamics interest me; ditto underage relationships. Muggle/magical or cross-species romance presents endless possibilities. I also enjoy tales of Hogwarts professors in love, and I've never met an older witch I didn't like (all right, that's a lie – mustn't forget Umbridge). I'm here for the characters, so I won't be disappointed if the fic's not plotty. Wartime is one of my favorite settings, with its exhaustion and personal risk and the shock of friends dying; also postwar, with its slow healing and its sense that nothing will ever be the same. If you can add magical touches, that would be a bonus. It can be as simple as housekeeping charms or as complex as a theory of the Dark Arts.
I'm a fan of description and take pleasure in language, so if you want to write (or for that matter, draw) elaborate paeans to imperfect bodies, I'm your audience. I love eroticism. I especially love when it permeates a story, whether or not there's smut. So go to town with the UST.
I also love Snape and will always welcome his appearance, but I understand if you don't feel the same way.
Dislikes: Voldemort wins scenarios. PWP. Next gen and essentially empty characters. I'm not all that interested in the Weasleys except perhaps for Percy. I'm not all that keen on Death Eaters, either, but if you choose to write about them, I'd prefer them to be dysfunctional and beset with personal motivations—in other words, not idealized—and by the same token not stupid, depraved, or gorgeously aristocratic. I don't much care for Pottermore, but if it inspires you, I won't object. Just, please, portray the characters with respect and affection whatever their size or age, and we'll get on wonderfully together.
