I wasn't able to vote in this challenge but I wanted to let you know I was dissapointed in the results of your photo. I was positive it would score very, very high - I like it a lot!
i like the image, but feel it is a bit too abstract for me to be able too readily relate it to the challenge. this is really one of those damned-if-you-do-damned-if-you-don't type shots...
These are stopped on the rise? Are these outdoors? If outdoors, how come the sky is green? This was a tricky one to attempt. Looks like you needed a little higher shutter speed to totally stop the motion, especially the bottom third area. Great idea. Good luck.
The essence of a motion capture is to give the feeling of motion without blurring the subject. I don't get a sense of which way the bubbles are traveling.
