Byakuya ftw lol I love it, my only complain is the brightness of the left. I personally think you should fill that in with something, even if it's just the same background
Wow... o__o You really are coming along in the course of one night. The background is nice... really nice. It flows well and the colors work nicely. You managed to blend in the render fairly well, but it could do with a bit more. Try maybe a calm C4D set to color dodge or linear dodge that would make the render feel more like a part of the sig as opposed to it just being slapped on (not that it looks like that as is). Only real complaint here is the text is a tad hard to read. Other than that, great job.
Dude, you really are pooping out the tags tonight ain't cha? lol Anywho, I like the negative space on the side, but you should make less of it, and put some white negative space on the right as well. I'm having trouble seeing some good effects done on the stock though. Try distorting it a bit.
Guys, I'm glad you like the signature. I'm still getting started in this sig making business, so I'm not very good, heck this is one of my first sigs. I'll look out for everything you've suggested, and work this sig a bit, perhaps the use of some blending for the stock. @Hissora : Yes...I have been, since I'm kinda like a noob in this sig making. I'm honored that you checked my sig.
