Concept art - Pirate Ship crew

I attended to a Concept Design course during summer.
Our final assignment was to make concept design of four characters.

First character is the Pirate ship captain Mei. She is a positive and warm person.
Second is Jasmine. A demon is trapped inside her. She wears a protective amulet to keep the demon under control.
Third is Bruja - a witchdoctor.
And fourth is Bijan. He use to be Jasmine's bodyguard, hired by Jasmine's husband. They had an affair and decided to runaway together.
