'Inside the Character' [Edath]

I feel like I always draw my characters with a sarcastic/aggressive mood, so I thought it would be interesting to change a bit what the paradigm. Here's Edath (the braid hair girl xD). The skin makeup is already being too much used so her skin is a bit morbid .-. but anyway, it was done with makeup and colored pencils + markers on her hair.
I didn't use any reference, although I had this idea on my head and I'm pretty sure I've seen something similar before xD
