Most of us think of nightmares as scary dreams, not fantasy creatures. The idea of a nightmare as a mystical horse is a fairly recent notion, but the fiery black creature has become popular in contemporary fiction and games as an antagonist or hostile spirit (true to its name). The most striking feature of the nightmare is that its mane and tail are composed of fire. Sometimes the creature is credited as breathing fire, blowing smoke from its nostrils, or even having flaming hooves. Fire can be a challenge to draw, so this lesson will explore adapting flames to work convincingly in place of hair.
