I’d try to Google “graffiti art” and find some websites. They’ll give you tips. Otherwise, it’s quite easy – start with a center point – a word, perhaps, or a doodle, and work outwards from there. Use bold colors and shapes and try to work with things you know best, developing your own style. Practice, practice and practice and use paper, not public surfaces. or find below some nice examples of Graffiti for your inspiration.
