The Slayer

This is an illustration I did for Spring Publications in Taiwan as the cover for the novel "The Slayer".

"The Slayer" is the sequel to "The Exorcist Teacher". The girl is also coming from the previous works but she turns to be a collage student!
In the cover, you can see her jacket is broken because she wrote amulets on it for firing the magic power. I'm wondering what it would like when the jacket is undamaged, therefore I drew a doodling for it.
