I liked 18 more precisely because the background was less distracting. The background is cleaner and lighter and less recognizable and less busy looking which means you can _see_ the foreground text, which should be the main object of this whole thing anyway. I do also like the textures of 14 and especially 20 but again they are slightly darker and more distracting than 18, and they may still be more busy (therefore distracting) even if lightened up to the overall brightness of 18, I dunno, have to see it to tell. In my opinion a background should not be in too much of a competition for attention with the foreground, that's all.
Anyway, that's my reason for picking 18, but whatever you guys decide is fine with me, I like them all, really. Great job! Dave
