Errm, okay. The render is a bit low quality. And I don't really understand the lines, they just confused me. Try to blend it more in with the background, because it seems pretty 'out there'. The text is good though, and the background too, I would just suggest the blending and a higher-quality render. Sorry if that didn't help at all.
Take out the lines from the neck and head, cause it's not doing much, But, keep the lines on the torso. the render is over sharpened, low quality, or both. Also, it's too dodged. Burn it with the burn tool a little bit, and burn(or erase) the white around it too, because it doesn't match at all, and it kills teh signess. Your depth is lacking mainly because there is NO focal effect besides the line, an next to him on the right, which creates a very boring scene. What I suggest is getting some splatter brushes, and making clipping masks. If you need help with that, get me on MSN. The render isn't blended into the sig at all, which is another downside, because it looks very sloppy and slapped on. And the text.... is just downright awful. It's slapped on there, no very well thought out. It looks like it's dodged, and facing a way that makes 0 sense. Only flip text if there is flow, and make it go in that direction, but even then, it still may be disrupting your tag. This needs alot of work, and it is far from your best. Keep at it.
You've done waaaay better. The render is horrible quality, that black line is just out of place and the text is horrible. 6/10
I'm sorry, I say it how I see it, most of the time he has very good sigs, this time, however, it wasn't good. Probably just because he was doing it while bored at night. I still like his other sigs though.
The text looks like you lightened it then overlayed it, too plain. Try making it more of a bold color or slipping it into a corner. Also, if you're going to do lines makes other vectory things so it does'nt look so...random. It's not your greatest, but keep working hard.
