Yes, she's a very serious character, no fooling around with her! ^_^ The medium used is Copic Marker, and a little bit of Prismacolor pencil.

Cassiel by @niteshadepromise (Ali)
Conceptual art for another character in the comic Demon City/Angel Night. One of the archangels, Cassiel, was scarred by the sin Pride, the only thing that keeps her going is her vengance for the death of her predicessor, and the hope that one day the world will be restored.
I love her expression; she looks so serious. The shading and color is stunning. What medium did you use?
