WOW, thanks for all the great comments everyone. This is my first entry and your comments really helped me a lot. I'm sure there will be many more entries from me in the future. To digitalknight, I did try cropping the picture differently so the circle wasn't centred but liked this version the best.
very cool, do you have an outtake where the center circle is off-center? The centered composition is the only thing I would change - excellent photo and great creative vision - 8
