Wait...so you ENJOY being toy? Graffiti IS bombing, period.
Sure there are writers who do canvas, clothes etc. at some point, but they do, or did Bomb. Vare doggie, you are NOT at that point. You NEED to Bomb, if you want any respect, or recognition. Sketching is not "pieceing". When you get to a wall there are no rulers, no pencils or erasers. Just the wall, the paint, and any skills you have aqquired.
