So subtly gorgeous. I can't look at it and not see the trees gracefully swaying their branches and dancing. I don't remember seeing this when I was looking through the challenge earlier this week, not that I was voting anyway. I'm sure glad others took notice and put you in the top 10.
You made a great choice leaving they misty greyness rather than pushing up the contrast and making the trees darker, which is probably what I would have tried to begin with. That would have easily made this too cluttered.
I love the tones. I sort of want a slightly closer in crop, start around 25% of the way up the photo to get rid of some of the lower trunks and really focus on the beautiful branches. Still, it's a very beautiful photo.
I don't know what to say... This photo is so mysterious, I'm almost stunned! I would've liked to see the ground, though. I'm finding it hard to believe that the ground would've ruined this photo.
