I had this idea for this horse in my Powderburn Post Apocalyptic setting, she carried this air-filter tank device so she could explore some of the more poisonous areas in old subways and ruined cities. Never really did much with her, but thought I'd do some more art of her and put her up for sale, so expect more art of her!
