Never satisfied #2: The Advocatus Atheist Book (Update)
It was suggested by a couple of people that the bridge image was too busy and a little jittery for the eyes. Although I personally liked it, I could see how some would definitely find it too much. So I went and scrounged up another, softer image. Hey, don't say I never listen to constructive criticism.
Now, as I compare the two images side by side, I see they were right. This image is much softer, much nicer on the eyes, and would look beautiful as a paperback book on a shelf.
