I know Halloween has come and gone, and believe me my decision to make this eye concept had nothing to do with Halloween at all. I was actually watching a movie called Beetlejuice. It was a scene near the end of the film where Beetlejuice tried shutting the mouth of Barbara to prevent her from saying his name three times. Beetlejuice whacked her with a metal plat framed zipper to zip her mouth shut. Anyways here is "how to draw a zipper eye", step by step. If you love the zipper style concept design art, you would enjoy this tut!
