Thank you very much for your comments, I really appreciate them.
Most of you have suggested that cropping above would have improved the picture, eliminating distracting/non-interesting elements. In some aspect, I agree with that, in fact I tried this before posting to this challenge, but to my taste the picture got even less interesing, so I prefered not to lose the signal echoes. Probably in basic editing there's not much more to do here. In my opinion, the problem with this picture is the picture itself :)
Nice shot. The title of your shot would hold more if the horizon (and other land based objects!) were not in the frame. Maybe shoot up a little more or crop it higher (from the bottom) I like the blue / blue / white composition though.. well done!
This is almost surreal in quality, especially with the background figures echoing the big sign. My first impression (for what it's worth) when I saw this image was: Hey, he's walking on piano keys! Anyhow, it's good seeing and a nice image - maybe a bit overexposed at the bottom, but still, fun.
Not sure I understand this photo but thats probably because its an unfamiliar sign. Excellent colors and clarity but I also find it lacks interest. Good luck in this challenge.
