Oh I love that... i really love that. I like what you did to the text, lookls much like the Half Life two text itself Thought im not sure about the border, seems to plain, but still really cool. I would advice moving the half life two logo in a bit more and blend it a bit But overall a great sig, i havent made a sig in a long time, but that's awesome 9.4/10
Really nice, love the half life font, i agree the border is a little plain, but apart from that! 9/10
awesome theme man! 8/10 the render however looks like he just got bit in the gnads by a space monkey but that's just my opinion. Gj on the colors.
