Your photo looks very surreal. In some respects, the... smoothness of it makes it seem more like digital art rather than a photo. It's a great picture with good color contrast, just looks a hint overly done on some of the filters to me. I think it will do quite well in the challenge though.
if I were a betting man i'd say this is William... and I am... so... congrats on your top ten (at least) finish will! lots of perdy colors in this one.
Unreal colours! Love it - great shot with lovely sharpness in the rocks contrasted with the milky water. There's something in the way of the bridge that I can't work out, but there's nothing you could do about it. I hope this one ribbons because it's magical.
