I like it a lot, the backgrounds are amazing, I also love your font, I like the picture that you chose for this sig, because you see Dawkins showing a little emotion which makes the sig that much better. Keep up the great work my friend.
The color scheme is nice, and the background is pretty good... I don't think I like the vertical lines a lot, but the curves are good looking. The picture of him is a little difficult to tell what's going on though because it blends into the background so much.
I don't like it at all....that green is just not kicking it I'm sorr. The brightness does not go well with the font and u can hardly even make out the cursive font. The bg is alright though because the swirls attract u to it. But besides that I suggest a v2 of this sig aswell.
