Suck at photoshop? No worries, CMY KILLA is about to drop some science on you with a little help from his crew Masta Bevel, Lens Flare, Filter Phil, DJ Dodge, MC Burn, Rastorvizer, and the rest. They have more filters than a T-Pain album and will have your mock ups bangin' in no time.
What's that? You have a question? Yo, shut up fool, no talkin when I'm shoppin' that's the number one rule!
