still kinda toy graff stuff but its a good start, the graphic art shit is dope though. work on your letters more and the flow between them is my only tip
For the graffiti, they have a dope fill but work on structure for the letter, each letter is composed of bars, and you want to those bars the same throughout the piece, and just bend em different ways, try different styles, then add some hook ups and a dank fill and you got a sick piece, this is a really good site for help with it-http://www.mindgem.se/forum/viewtopic.php?f=6&t=41
