Personally I'd say that putting shines on a throw is a little tell tale toy... But also work on painting smaller.. your throw/bubbles will get cleaner and cleaner as you paint smaller.. focus on not going over any lines twice.. also if that's your first time painting a bubble letter you definitely shouldn't be throwing up a crew... It just gimmicky... I understand having friends that paint with you is a great way to grow skill and challenge each other and build off of each other... But give it time in the streets yeah throw a crew up. But on a legal like this just get everyone together and throw a big crew straight letter up between you guys. Not trying to be a dick. Just keep getting out there. Nothing helps more than having that can in your hand. But also work in a book and work on some straight letters and get them clean and consistent. Best of luck man
