Really good one! It must have taken ages to get the focus right! And the colours are great too! Great!

nice

well done.

great

Fabulous

great entry

Nice shot ! Some kind of Ying and Yang ... With bright water upside left, and dark water on the right ...

very nice find, great entry and nice "s" curve!

Wow! this is a fantastic entry!

Oh, I just love this one! The colours are so dramatic, and yet the scene is so calm. Really good shot. I also like how the water is wavy on the right and calm on the left. Very nice shot. =)

You got it right!!!!!

man made element in this shot. perhaps you can re-shoot from different angle?

Well, it is not clear for me "It just cannot be man made, or feature any man made parts". It is about the bridge that can not feature man made part or the whole picture ? Sorry!
Here, you can see a natural bridge.

the guidelines are a little unclear, but I would take it that the 'bridge' cannot feaure any man made parts.

It's a nice shot and framed well just really blown out in the sky.

Lovely

excellent capture...dof, contrast, light spot on! well done.

nicely done, good entry...good luck!
