Hey, this is cool! You got a lot of nice comments, too! (I didn't even vote this Challenge, unfortunately.) You did a great job capturing the motion in this! I'd like to see the original, too.
I think some increased contrast would have helped this one out a lot. As it is it's a little too flat inspite of being an interesting subject. Doing it in color might have also helped it out. After the challenge, I'd really like to see the original.
