This rattler was irritated and couldn't make up his mind to strike or not. So he started, but didn't follow through. Note how the shadows show the front portion of his body is lifted up off the sand. At 100%, the snake's body is quite sharp, while his head is significantly motion blurred. I'd have preferred more room on the left, but I had to go with what I had when the snake looked like he was going to move. At least the top and bottom give him some breathing room, plus they leave room for the masthead and article names when my fantasies come true and this is used as a wraparound cover on a magazine!
