Yes, you're right. There is a lot of shadow and light play in this upload. Some of the newer software out today has fixes for overexposed and underexposed areas that might be helpful but for sheer contrast and composition, you've presented a nice upload.
I particularly like the contrast of the tall dark trees with the lighter shades of greens.I would like to see how it would look without the little fallen log/bramble area on lower left, but overall it is a very pleasing picture.
