Great shot. The title might be great if you phrased it right: "Throw Caution TO the Wind". A tighter crop of the caution ribbon, cuttong of the grass on the right might've worked out better.
Seems like me some time, just blowing in the wind :>) Tough shot to isolate the background. As hopefully constructive criticism, you might have tried a longer focal length for this shot to get a narrower viewing angle, and shooting from a higher position. This technique would have yielded more of the grass and less of the trees as a background. Just something to think about for the next challenge. Use all of your tools. The exposure is great. Great concept. Well focused and sharp. Composition is all this photo needs. Good job.
This would've been better if there was some idea of what the tape was for... Just having a caution tape in a field doesn't make much sense, it leaves me sorta wondering what's going on.
This is certainly my favorite shot. Great idea, great execution. I love the focus, the colors... everything. Good title, too, though I would have enjoyed it much more if I had been forced to figure it out myself. It's too bad so many people won't get it.
This is a good example of the challenge topic. I also really like the texture you have captured on the fence pole and the fence itself. I don't believe I can comment on how you could improve this particular photograph. Maybe a more dramatic subject. I know this was a diffucult challenge. I had a hard time with my subject as well.
