Hi, I'm Pays164. Here's some tips on how to do graffiti for beginners. Don't get too caught up in trying to get all wild style when you're still trying to understand the concepts of bending your letters, and getting your graffiti done. So basically, keep it real simple. Blockbusters, mobile styles, throwies [SP], all that is probably your route to getting a good style together, before accomplishing something like a wild style.
Secondly, find a place to do this. Look for places in your town, locally owned businesses that will give you permission to go explore your graffiti talents, and try to do stuff like that. So as you get better at these simpler styles, and start to understand your own style, and bending and torquing these letters out, you will eventually build up to a wild style. Another good tip for the beginning graffiti artist, draw, draw, draw. There's so much you can do just by drawing and developing your style at home, before you hit the streets and show everybody what you got.
