Okay, I'm really trying to think on this one as I really like the composition. I'm trying to figure out what was moving around the image to meet the challenge requirement. I'll have to check it out at the end of the challenge and I don't want to (nor will I) DNMC it as I think I can see a couple of spots of where the stop action took place. Nice comp (again). 7.
Details: Long exposures can often create very dramatic effects in photography. Use a longer than normal exposure to create the impact of your image.
