Mystery Group

This is an old one of my drawing that i decided to post up as i flipped through my drawing binder. This is a group of my supernatural detectives that i made a story about. The girl with glasses is Nicole, she's the bookworm of the group. The guy in the middle is Tyler is a creature called a shade(i haven't thought of the details about his species yet, but i think of sometime. If anyone wishes to donate idea, please do.) . And the girl with the pigtails is named Samatha, is captain of the high school's track team,who is not really one of the detective but one of the people who snoops around the detectives' work.
