ur graffitti (like any other art) should start small... if uve never done it b4, what makes u think ur ready for a "wall" ?? i still do it once in a while, but i dont go taggin trains an stuff..lol.. u should buy an 8" x 10" black book with all white pages and check some graffitti forums.

Agree with that. start small and spend time searching for other pics of graffiti. it goes without saying not to bite someone elses style but study how certain pieces grab you and break it down as far as how that piece is made up. Look at the colors, how they contrast/compliment, letter positioning, how the letters all share the same "style" to make a cohesive piece. I dunno, I used to just study that shit and then try my own.
I stopped with graff after i started transfering from the black book to walls. Never really mastered using cans but I'm pretty solid with sketches.
Get colored pencils and markers too, you can start off making some dope sketches to figure out your style before you start throwing anything up on walls.
You got any pictures of your graffiti paintings?
