I certainly understand everyone's comments. They are good ones. For me on the other hand - I brought up the image and was looking at it. The detail of the rock wall on the left got my attention, along with the coloration difference between the left and right. I found it very calming. I can see this hanging in my office - so that I can just get lost in the picture. For that aspect - I really really like it!
Then, I started reading everyone's comments. I do agree and I did learn - as this is something that I would have shot, thinking that I just captured a fantastic shot.
The crop makes it feel like a totally different image. I just hate loosing the left hand wall - which was the most interesting to me. I am wondering if you could crop perhaps 4 different images out of this. The right hand side as you already did. But, perhaps a left hand side, and possibly 1 or 2 vertical crops?
