that looks really cool. And i mean it.

This must be one of the first dark signature's i've really liked. Mos areas of it works well.
The text placement was a really neat idea.
2 things you could perhaps fix up. The areas around his hair look to pixely.. perhaps fade the sharpness there and maybe include a border.

i feel like you could maybe crop the ends a little bit since they are rather blank but also keep in mind you dont want it to feel to square.

Wonderful effects, but I was thinking you could actually try cropping it in line with the effects, so that you have more of a U shaped sig.
Just try it out, I have no idea if it'll look alright, but try cropping it slightly in one way or another.
It's got great depth, but the lack of luster/colour on the side ruins the effects in the middle.
Nice, nice, nice work!

Cant say that I like it, sorry
Its too dark, the white stuff looks like low quality and the render just doesnt fit, also theres no border, but I see you never do that :P
Keep going

hmm... its nice, except the c4d part, the c4d below his face is worsening him off. i like the black part. the text looks good on his tounge, but! some colors can do the trick. Just a pinch! i hope u got what i said
