The quality didn't really improve... Well whatever, the background and other c4dish effects don't really seem to blend with the render IMO. I like the Idea behind the text though, i love multiple lines
Thumbs up for the render, and you've created quite a nice flow for this tag so I'll say something nice about that..(I just did)
But seriously, the background stock doesn't match the colors, and I find that quite a waste because I believe it makes this sig less good.. Sorry for the sucky c&c
