No one word to describe your style. I love that your sketches have purposeful lines, rather than the popular "scribble until shapes take form" appearance. Each piece is well contrasted, yet soft, delicate. Even your detailed pieces have a simplicity to them that is modest and amiable, not dull. It leaves one with a craving. Just the amount of tasteful detail, voluptuous features on your characters (eyes/mouth esp.) give them a sense of innocent melancholy that makes your style addicting.
