Cory Casella, an artist based in Birmingham, Alabama, has a talent for drawing with a single continuous line. He puts his pen down every once in a while to rest, but picks up directly where he left off, never wavering and leaving the line unattended.
His artwork to date mainly revolves around the theme of animals and insects, having drawn the side profiles of fishes, snails and butterflies among many others, all with his distinct and elaborate style.
His works have gained a massive following along the way, which has led him to set up online channels for his fans to buy his work.
