How to make a good creepypasta OC (reviews closed!) (old, like REALLY old)

Looks

This one kinda goes with clothes. Ok, so this one you can't really get wrong. But be careful because it can be easy to go into Mary Sue territory.

With looks you can basically do anything, blond, brunette, redhead, dyed. Yeah, I don't really care about the unnaturally colored hair thing. But, make sure that you have a good reason why they have that color of hair, like they dyed it. Or they have white hair because they're an albino. (I've never seen an albino creepypasta. I'd like to see that)

Now with the eyes, same thing, unnatural eyes aren't bad. They could have colored contacts or a special syndrome. (Seriously, there is a syndrome that makes your eyes purple(that is also fake apparently)) Or again, they could have red eyes because they're albino. (Still would like to see that!) they could also have a special thing with their family where everyone in their family has oddly colored eyes.

Like my creepypasta has light brown hair and navy blue eyes just like everyone else in her family.

Please, for everyone's sake, don't make their eye color change unless it's with changing contacts. And don't make they're eyes glow. And if you're gonna give your character Heterochromia (aka two different eye colors) please do research and make it realistic. Or just make it where they're wearing contacts.

Ok, so other features. Scars, freckles, birthmarks, tattoos, ect. Have fun with that. You can basically give them anything that falls under that stuff. It's ok if they don't have any flaws like that, but it makes them kinda boring if you ask me.

And gender related features, don't make them have unnaturally large boobs or other stuff like that.

So yeah, this is the one of the spots where you can end up making your OC into a Mary Sue. So be careful and be creative with this.
