I'd like to see the version with the shadows opened a little. I suspect it will be hard to maintain the high drama of the version you originally posted.
The odd thing is, if I look at the shot on Flicker w/my iPhone 6, I can see what I intended to create, with a hillside clearly visible in the background, although it's very subtle (the way I wanted it to be).
Here, it looks like pure blackness.
Same with looking at Flickr with this computer I'm on now.
Maybe the iPhone screen is really just that much better?
I'm confuzzled.
