yea deadly, i'm not gonna lie you're making proper progress. Don't put that on stickers, but paint that with spraypaint. It really isnt good enough to be on a sticker, because stickers are really supposed to be ur A+ game, and ur A+ game should be much better than this, no offense intended.
But if you were to paint these pieces really big, you would get a lot of good practice using the can. Considering how simple the letter structure is (which btw you need to work on, just try and make all hte letters look the same, but obviously maintaining the letter that they are) you should have no problem painting this somewhere... I don't suggest playing with outlines and borders when you're first starting off because its a million times harder than it looks to paint ur piece.
In soon time you'll progress, and you'll pwn all the graff noobs, and then parkour your ass away from the crime scene..
i'll design some next shit, and maybe go bombing some time soon, right now i gotta get rdy to go out to this pro skater tour... these dudes are in my neighbourhood and theyre gonna be skating at a local skatepark... and im definitely down for that.
and again, to the guy that painted his neighbours fence, if u tagged a cops property, thats automatic heat on ur name.. but im pretty sure u were smart enough to change names since uve done that.
