This photo's emphasis is the glowing very dark circle in the top right. This one shows darkness very well. The dark jagged circles on the edges on the paper show impending doom as the grow closer and closer to the glowing circle. You can even see that in the circle that its already being corrupt. The background patter is also intend and goes with my theme. There are many jagged dark lines in the background. Overall this would probably be the darkest of the four I made.
