#so don't take it as gospal but this is what have have stewing in my brain right now

Okay, drawing is hard and I'm horrible at drawing full body references. The face is the most important part and I've decided y'all can imagine his feet on your own. Anyway...

I was going to do biblically accurate Sans for How to Make an Artificial Companion, but have changed my mind. Rough sketch is rough, but you get the idea. Ramblings about it under cut

So, Undertale as a game (or monsters in general) don't exist in universe. They're all AI designed by humans or in a few rare instances (*cough*Mettaton*cough*) other AI. While they should all be recognizable as who they are by a real world viewer, there are some notable differences on their designs because they weren't originally pixel art but instead 3d models and there are some signature details depending on who made them, when, why, and where they pulled references from. Sans (and Papyrus later) are made by a character who 3d prints chibi models and sells them online. Reader asks them to make a skeleton, something realisticish because reader is going to be staring whatever they make in the face and something that's one third a head would be weird, but not too realistic because talking to a Skyrim skeleton would also not be ideal. The artist is going WAY out of their comfort zone so the model is a little odd but loved dearly by everyone. This is why he's especially cartoon-y, and his anatomy is simplified, and has massive eyes compared to og Sans. I don't know if anyone else has looked up skeleton characters, but Sans also has a really fucking unique face shape. He is not made for being 3d with an opening mouth in mind, so while I was tempted to keep the shape, I ultimately changed it. He still has a massive smile, thick blocky teeth, and a roundish skull (especially compared to Papyrus) so hopefully he still reads as Sans-like. This is an au, so I feel altering everyone's appearance is acceptable anyway.

Lil details. His sternum is purposefully shaped to look like a tie because sternums are kinda shaped like that and I think it's silly. He's very much made to look cute and avoid uncanny valley while still being a personable and expressive. He is able to control his eyelight size or make them disappear, and later do specific expressions kinda like a V-tuber (so you get comical heart eyes or sweat drops kinda thing, but he doesn't use those unless it's for a gag and even then it's rare). The reader also makes him shorter than them. He starts the same height when he's a slim target mannequins, but once they're messing with his form they make the top of his head reach about heart level so he isn't as spooky. He starts off naked since they don't have monster costumes and his body is not considered sexual in the slightest, but eventually they do a dress up thing with him and this is when he picks up his signature outfit (after submitting many bug reports because wow this form is sand in the gears for everything this headset was made for). He actually prefers to stay dressed after this because he can make himself look chubbier which he thinks make him more friendly and approachable. He likes the form he was finally given, but the focus on the iterations before the final and just what he looks like in general gives him some self image issues and a fixation on keeping up appearances. Of course, with this fixation, he keeps it pretty down low which makes it hard to spot so you wouldn't really guess.
