Line Study - Santos Gaitan

Line is such a simple element but when used well it can be very powerful. In this piece by Santos Gaita he uses line in a way that sort of tricks your eye at first. When you first look at this drawing it seems to be a piece of fabric becoming unwoven with the string at the top but when you take a step back and look it's obvious that this "fabric" is someone's shirt and the single string is actually the profile of the person wearing the shirt. Also, he uses straight lines to create shading in the shirt which are simple but effective.
