Considering you're a more experienced member, I'll be a little bit more picky on what I think could be fix. Of course, the sig itself is looking great but I'm sure you could work on. The "white snow" doesn't look that good on that. You had some grungy textures so I would have stayed with something more sharp. The font is cool but I would have added some sub fonts to it. Maybe some dark borders too, but not sure about that. Overall, good work.
