Interesting. The overexposed, contrasty rocks and vivid colours give this photo a real sense of drama. It mostly works... it just seems a tiny bit overdone. Too garish.
The sky is a very pretty blue. The rock though is strange to me. I am not so sure I like the very very dark shadow in the center of the photo. There really isn't anything to help us judge size on these either. I know with nature objects, it's often difficult to do that though. The colors in the shot are nice. Focus and clarity seem good too. Good luck in the challenge.
I have problems with the coloration: the rock looks like it's bleeding.
I like the strong contrast of the left rock from its sunny side to the dark side.
I really like this. Interesting composition and textures. I love pushing colors in photos...but i think you may have gone a tad far with the blue here. Maybe you could post the original after Sunday..I'd love to see the unaltered image :)
I can't imagine that this rock is naturally this red. The sky looks artificial too. Really interesting rock formation but I would have liked a more natural look, especially for this challenge.
