Meh, i dont really like this sig on the basis that i just dont like grunged up sigs, there isn't much focus on the focal and there is little or no lighting. but hey, thats probably just my preference.
Very nice. Great job.
Nothing I can really see that I would do differently.
If you want, as a suggestion, try to make the same white appearance
that you made on the game on the middle. Just to see how it looks.
Otherwise, I wouldn't do much to change it.
focal point is misplaced.
grungyness is whored.
text is disgusting.
lighting is wrong.
no depth.
shitty chaotic flow.
fucked up colours.
dumb 1px border.
^ squidge is mostly correct, however vulgar he is, though firstly, you have two focal points, secondly, there's no distinct boundary between foreground, middle ground and background (usually blurring working pretty well), and the colour scheme could be greatly improved.
