That said, this looks nice and I'm impressed with how well it turned out. Even though continuous line drawing is a common exercise it would be hard to pull off a picture as nice as this without a good amount of preparation.

Again, its a one-stroke drawing. Its supposed to come out like that. Unless you're a master artist or using a machine, the path is supposed to be erratic. A sneeze, a cough, a random hand twitch, etc will all cause errors and you're not supposed to fix them in a one-stroke drawing.
