In his drawing, McCay made bold, prodigious use of linear perspective, particularly in detailed architecture and cityscapes. He textured his editorial cartoons with copious fine hatching, and made color a central element in "Little Nemo". His comic strip work has influenced generations of cartoonists and illustrators. The technical level of McCay's animation—its naturalism, smoothness, and scale—was unmatched until the work of Fleischer Studios in the late 1920s, followed by Walt Disney's feature films in the 1930s. He pioneered inbetweening, the use of registration marks, cycling, and other animation techniques that were to become standard.
