Both are pretty good. Two's sharpness and color wins it for me.
1 looks like it mimics a skyscraper, but the sky is a bit too bright for me. The whole thing about this is the texture of the object, so I don't want any bit of that blurred.
2 looks like it mimics a cliff, but the color of the sky is too dull for me. I'm on the fence if the darkness of the wood works, but leaning towards it does because it makes it seem as if you are under a cliff.
Get rid of the black corners. If you're going to do that little thing photographers do, don't make it completely black, either make it a little darker or don't have it so prominent. You're trying to give me a balance with negative space on the right side, I shouldn't be distracted by the black corners.
