Honest review? I think the clarity (or unsharp mask effect) is too high. It's a bit glary and it's harder to see the rock wall because of it.
Also, because of the effects used, you're getting colours you might not have intended, lots of blues and the tree's shadow doesn't look real.
I don't think the actual look of the image needs to change. Instead increase the brightness of the two climbers (using marquee selection), bringing them out of the darkness, use the clone tool or a healing tool to try and get rid of that nasty lens flare down the bottom.
Do a
much more subtle unsharp mask because the image isn't in dire need of sharpening.
You might even want to use a gradient filter from the top right corner inward to darken that tree up in the corner and take focus away from it.
That's what I would do anyhow
