Being stuck at home has actually been useful. I have been playing around with the cover art for Filter, this is how it goes. All images copy righted by Gwenn Wright.
The picture at the bottom, with the eyes, is the original. The photo with no words was taken by me on my HTC Inspire while walking to get the boys from the bus stop. I don't know much about PhotoShop but did what I could. In the end, the spooky trees with the white lettering was the winner, for visibility's sake.
