Smiling pipes.

Love this! Print seems a little bit bright, but could just be the scan. What a great place to photograph children!

I agree. This is where an eye for such things is important. It's a bit like the pipes are benign guardians rather like the trees in various fair tales. At first I couldn't work what the pure white crescent moon shape was but I assume this is bright sunlight at the edge of the big pipe. If some texture could be dodged in here then a good shot would be even better.
