It looks pretty cool. I am not a fan of the background style though. But if you wanted a stamp, maybe your could of put a rectangle without the middle round it. Its in the custom shapes and then maybe add a texture or something. But it still looks cool Good job.
Just to let you know, you don't have to triple post. There's an edit button.
For the stamp thing, I think it'd look really nice if you got some brushes and made it a little splattery. The background is weird in my opinion. Looks very MS Paint-like. Other than that, nice job. 7/10
If I were u I'd do like some of these guys and make a sig that's just got your name and game as an identity...then post all the server info underneath your "main" sig..
To much txt, not enough cake.
Plus that cs image is used alot around here.
