i like you signature image the most aswell as the demon one becuase they look the most profesional but there is one thing missing in nearly all of your images. FLOW such as the one holding a graffiti can, the eecting shoudn't be going straight up but at a angle and on some of them the text looks like it has just been placed there not really trying to blend thats why i like your signature the text works aswell as the flow.
the sigs 3 - 5 are a year old ... aka... i was more noobish then lol.. the first 2 are more newer XD i just thought i should post more then 2 pics up there though .__.
