Been linking this through Dropbox to a number of people, figure I might as well upload it publicly. Anyway, until I get a proper reference sheet done (which I have a plan for!) this is what I'm calling my "proto-reference".

I'm pretty set on most of this, but it is subject to edits if I decide things aren't working or if something from a once-off works so well I decide to make it canon.

Anyway, art notes:
- (All) Body shape/build - She's pictured here in the Them's Fightin' Herds style, which I adore, but somewhere between there and a more realistic reindeer who's a bit on the thin side is fine. If I'm commissioning you I probably like your style of deer, so don't change it too much!
- (All) Antlers - Six point, crescent shaped, present year-round.
- (Anthro specific) Feet/legs - Always digitgrade/unguligrade anthro (hooved, satyr-like legs).
- (Anthro specific) Hands - Heavily prefer hoof hands with two fingers plus a thumb in the blue of her hooves/antlers
- (mostly for NSFW) Udder - Has a petite but visible deer udder. It's full of rich eggnog.
- (All) Materials - If you can do rubber/latex, Lus loves to be a sleek and shiny synthetic deer. If you do food characters, she's been known to be a chocolate and whipped-creme deer. If not, fur is fine too!
- (All) Accessories - An eartag bearing her nickname "Lus", worn on her left ear (her off side). Pronouns (she/her) also nice if there's room on the tag, or possibly other things to be discussed. Not always present, and doesn't always need to be readable, but nice to have.
- (Anthro-specific) Clothing - Prefer either enough fur to be considered modest, or an elegant dress with a hole for her tail so it isn't uncomfortably constrained.

Non-art personality notes and such (If I've linked you this for art instructions, you're welcome to stop reading here):

Illusory Rangifer, who typically goes by just Lus, is a reindeer doe (she/her pronouns) who floats between anthro and feral forms. She's a bit timid and a bit flighty (she's got some deer instincts, even as an anthro), but also curious (sometimes too much so). In settings where she's comfortable the timidness can fade and she can actually become quite chatty, and at times even a bit flirty/slutty. She has a bit of a flair for the elegant and a dislike of dirt and sweat, which is part of why synthetic forms with floof that's always perfectly molded and a shiny skin that easily wipes clean appeal to her.

Her primary/secondary/accent colors are dark brown/tan/sapphire blue, as shown. This is a constant across all forms (as much as possible).

She has some limited magic abilities, which her antlers serve as a conduit/focus for. These include some small ice magic (for keeping cool), some telekinesis (mostly used in feral form since hoofs are less useful than hoof-hands), and some transformation magic (for shifting between forms, and maybe transforming others).

Her udder is a little larger than average for a deer, but still small overall. Instead of deer milk it's been enchanted to produce a rich, luxurious eggnog, which she bottles and gifts to friends or sells at a local farmer's market as a tiny little side-business under the name/branding of "Caribou Creamery". Asking to "sample from the tap" is a good way to get a cloven hoof to the face, unless you're a good friend.

Her exact background varies since I've put her in fantasy, present-day, and sci-fi settings and can't keep 100% consistency between them, but there are some common elements. She's from the outskirts/suburbs of a larger city, so she can be a city deer, but also get away from things and embrace her cervine side. She's modestly successful at some type of unspecified artisan/white-collar job, which makes her more knowledgeable on techy/mechanical things than is expected of a cute reindeer doe. She's generally fine with the quiet life, but occasionally dreams of stardom and/or adventure. She isn't a fan of the heat and prefers the cooler seasons, but has mixed feelings about the winter holidays since she gets a lot of attention just because she's a reindeer.
