Elizabeth, for me the painting is harmonious and color recession is correct and well handled.
I'm confused about the lighting. Is the day overcast? If so, why the dark shadows modeling the tree on the right? If it's not overcast, why not similar shadows on the other trees?
The painting does not "read" well for me. The dark verticals on the tree on the right (and none on the tree next to it) serve as a frame that keeps my vision in the right sixth of the painting.
I assume you wanted a painting of an overcast/slightly foggy day. If so, I would key up the values in the darkest darks and key down the values in some of the other midtone darks. Were it my painting, I would make some minor changes, lightening the right tree and darkening the others, and doing a liittle more value contrast close up:
That being said, you've done a great job simplifying a forest tangle and I like the painting, a lot.
