When you're starting to learn to graffiti you will spend a lot of your time looking at other writers work and perhaps even copying a few to help you figure out your own style. Most new writers learn to graffiti by copying other writers' pieces. This is all perfectly acceptable as long as those copies stay in your black book (sketchbook). When you start putting together your own pieces, it needs to be in your own unique style.
