Joe - this one's a tad bit darker, but not too much. I wonder if your monitor is a bit brighter than mine. I wouldn't want to go darker than this, at least as far as what I'm seeing on my end. Let me know what you see with this one.
When you said "a bit" you really meant a bit
I'm not trying to to convince you one way or the other but to my eyes the image begs for that really saturated, almost over the top look. Let the trees and mountain go black. You've got plenty of colour in the image, so don't touch the saturation.
This might not be a "portfolio keeper" but if you make it dramatic, I bet you'll get lots of oohs and aahs from visitors (assuming you have it framed and on display in your house or office)
And after all, we all like oohs and aahs
