Hi,
To tell the truth, I like both versions. At this point, I like the older one better. It has great subtlety to it. It was very ethereal.
What I do like about the new version is the potential. I think it can really pop with some more contrast. Kick up the darks, maybe some more browns. Possibly some little gems of blue sky popping through the trees. The ground definately needs "grounding". Give it some kind of weight or contrast. It looks like you want to go there, but are a little afraid. Just jump in and go for it, you can always pull it back.
I applaud attempting dense forest images. There is so much layering and gradations of colors to address. It is beyond what I want to attempt. You are accomplishing it very well. Keep at it.
Thanks for sharing!
