I think I saw another photo of what I thought were carp. I like this better but just not as abstract as I was hoping for. And for the 'Harmony' part - it seems rather chaotic to me. I do like the photo - I'm just not sure it's what I was hoping to find in this challenge. It looks like a painting which is cool to me.
Nice. I recognize the koi, yet the image is very abstract in the colors and lines. I really like this, and it makes me feel happy and yet somewhat frenzied.
Wonderfully photographed, reminds me of a classic impressionistic painting - suits the challenge well - minor quibble, perhaps a simpler title "harmony" would work better, but not important - great job.
