Thank you for this thread! Super interesting topic. 
Your villainess looks beautiful. Love her design with the flowers and butterflies.
What a great contrast to her behaviour, playing with corpses to get the attention/ followers she wants.
(If I got that right.)
@vapidink
Oooh, another one who likes to have dead people around! And who has no problem with killing even those who trust him, it seems, to lengthen his life. That's definitely a bad guy. 
The mask really adds to his mysterium!
@SirCoockie
Huh, acting nice, but being mean on the inside? Classic take, like it!
@AmysGames
Masks and riddles! So, it's not that clear if he's really the bad guy, even though acting chaotic/ harmful?
Interesting!
@stiatent
Ouch, two really bad threats! Wouldn't know if I'd prefer to encounter the sadist or the monster.
Well, I'd rather stay away from both.
@Lensing
Urgh, villains who you could actually meet in real life scare me the most.
Everyone knows these kind of persons, feeling rightful without any doubt, doing/ saying the ugliest things. Yeah, think she's a great main villain.
@Leyelle
Ooooh, like that! Understandable, I think, to become frustrated, even bitter, when you created, well, life, but then all is turning against you. Awesome take!
Now me. 
When it comes to my own story, it's a bit hard to say who is the villain. One of my main characters is a demon, doing really bad things. Still, he's not the main villain, cause in a way he's just like the other demons and does what it takes to survive (well, mostly).
So the Lord of Hell would be an obvious choice... But since He's satisfied with primarily watching His creations being cruel to each other (and to humans and angels, yeah, well, it's not a nice world, sorry), He's not the one I would call the main villain.
That leads me to His right hands man... Tazeel. A demon, of course, but this one is really broken.
Won't say more, but here have a portrait of him:
