Executed on paper, "Night Creatures" delivers an even greater emotional impact than her larger oils on canvas of the same period. One imagines that hidden within the thicket of Krasner's swirling black-and-white paint strokes are menacing eyes, heads, and even entire figures surrounded by dense foliage. Such suggested images are common in her later abstract work and grow out of her earlier, more representational figure studies and still-life compositions. What distinguishes this particular drawing—and others like it from the mid-1960s—are the raw intensity and primal power engendered from the figurative images and the artist's forceful yet controlled handling of the medium. The picture's haunting, somber color scheme, which includes black, white, and a touch of rust, along with its title allies this work with a series made from 1959 to 1963, which were painted at night and thus called Night Journeys.
Krasner's later work, from the 1970s and 1980s, reflected a new direction toward colorful compositions with large, flat, "cut-out" shapes and very little surface texture.
