Relax

The composition strikes. the sky looks dramatic, the valley shines in its green grass - what's wrong?

I think it is a little bit too dark. For instance, you STILL have the details among teh twigs of tree in the left corner, AND, you have a 'triangle hole' over there, so you could make it distinguishable as well.

Even the WB is right. Therefore right now it may not seem as much attractive as it could be.

Another approach (if you still can be there) is to try to shoot the current scene with a telephoto lens in vertical format, so you can totally get rid of peripherials, having only the chairs, rocks and sky. That should work either;)
