v2 is best, and a couple things bothered me here, i think u should change

the first thing that came to my head when i looked at the sig was that the edges of your render were too sharp and graney (hmm dont know if i spelled that right lol) although i like the graney effects in the bg

2nd, def, plz, keep that border out lol, its ugly :P

3rd, i think the txt def needs some work, try some other fonts and make it blend more in the sig, remember your txt is part of your artpiece, if u catch my drift

looking at it again, i think u should try applying the image, putting a slight gaussian blur to it, and then put it to soft light at a small percentage, try to cut back on the sharpness (unless your aimin for that, then go for it, i say just give it a shot )

u better try it out, cuz i just wrote a shit load here lol.
