In this tutorial, we learn how to draw bat/demon wings. Start out using a light pencil marking to make the outline of the wings. You will want to draw wispy lines and make them light to create a light effect on the ends. Once you have the outline finished, use a hard pencil mark to draw over it. Create large wings with hard edges and mark in lines along the middle and the edges of the wings. After you have done this, make sure there is another wing on the side of the wings and then shade to finish up the drawing.
