At the gut level, I find the first a tiny bit more satisfying. The two trees on the right don't bother me.
In the first, the small opening into the woods behind, just to the right of the main trunk seems to invite me to wander further into the picture, while the similar area in the second feels as if it is blocking me out. I'm not sure why, perhaps the color? The tones in the first feel more plausible to me, so I'll vote for the first (but they're both quite good).
