If not for the excessive JPEG compression artifacts that are visible, I would give this a high vote. Compression kills detail. Always use the least amount of compression that you can and still fit it under the challenge limit
I love the color and composition on this. Centering is particularly effective for me with this shot. Only problem is it's appearing seriously sharp on all three computers I use. I'm not sure if it's the intent or not, but it jars me a bit.
I really like this one. No fair - you pick one of the best all-time song titles and coerced me with it. (You may have sneakily used some type of "Golden Sections" in there somewhere.)
