Ah, well. First of all, it does look nice at first sight, mainly due to the nice layout and colouring. It doesn't seem very much original in my eyes, seeing as I've seen you use this sort of layout many times before, though I'm sure your just recycling CSS, but I wouldn't hold much against you for that - this signature has a load more potential, but for now it's very basic.

4//10, though like I said, there is potential of you learn more CSS.
