These are interesting designs and art style! Cool coat on the mist-headed person, neat hair on the middle one, and nice pants on the last one. That one's looking very nervous about something.

Very pleasant art style that you don't see much elsewhere! I can envision the first character to have interesting potential for emoting by the intensity and shapes of the smoke or fog coming from the collar, instead of relying on facial expressions.

Wish you a lot of good luck and fun on the comic project going forward!
