It's a tie between Snake91 and Superman64, allow me to explain a quick few things here:
Voting ended on the 5th AKA Friday at 11:59 PM (I just wasn't here to edit the topic and remove the 'vote' part from it.) so Sollah's vote, even though it's well written than half of the votes in this topic, didn't make the cut. Apologies to Sollah.
Classyman's vote also didn't count due to, well... lack of a reason outside of "Yeah! Bebop!" and even then most of the other votes were a stretch until I provoked an answer.
Snake91 could've EASILY won this if people would have taken the extra seconds to type out some sort of response outside of "FUCK YEAH! COWBOY BEBOP!"
Also, and this is a personal thing, I think THEME should play a very hardcore part in voting, although maybe I didn't really specify it that well in the description. Snake91's sig is VERY well done, and overall a wonderful design, and just all around a winner. However, from a 'cyberpunk' standpoint, the sig looks too much like Bebop and not enough like Cyberpunk. It's not dirty or gritty or dark colored or anything, it just looks like a Cowboy Bebop sig, and while it does fit the rules of the theme since Bebop DOES count as a bit of Cyberpunk, it just doesn't visually lend itself to the design.
Now, this isn't JUST for this sig or because I'm being biased or anything (and I'm sure it looks bad that I discounted so many of snake's votes, I swear to you snake I still love you, don't think I'm just being a jerk for jerk's sake.) This has happened with other themes before, where the design, while cool and awesome, just takes a render from a series or whatever related to the theme, and does something entirely different and/or unrelated to the ESSENCE of the theme.
If I took a picture of... Jerome Bettis (a famous football player and now news anchor) and put him in a field of flowers, and the theme was 'sports'. Sure, it's Jerome Bettis, and he's a football player, but... he's totally out of his element, fields of flowers have nothing to do with football or sports in general. That may be a bad example or too extreme of an example, but I think you all get what I'm trying to say. If Snake's sig was Spike, and the background reflected more of some of the cyberpunk cities found in Bebop, then it would've just worked better as a Cyberpunk theme submission.
Just my two cents, and all I'm really trying to say is "Vote off design, but PLEASE take themes into heavy consideration when voting too. It should be half design and half theme."
My response to this wall of text is...
Fuck yeah Steelers and Jerome Bettis. *FLEXES*
