I would pick the second picture and crop it to achieve a better balance in composition. This is somewhat on the subjective side, but you can usually see the difference in visual energy when comparing one composition proposal to another. So here is what I suggest: For a reference point, look at the right boundary of the first photo. It is just to the right of the largest of three prominent evergreen trees in a series leading to the left. Call that largest tree "Tree #1."
Look at that same series of three trees shown in the second photo. You can see a much smaller evergreen tree just to the right of Tree #1 (there is also a small tree in the foreground of Tree #1, but I am not referring to that one). Place the right border of the photo to the right of the center of that smaller tree with is just to the right of Tree #1. Maybe place the right border so it cuts off about 15-25% of that smaller evergreen tree that stands just to the right of Tree #1. So then you see about 80% of the smaller tree, and all of the three larger trees including Tree #1.
The top and bottom borders are fine. You want that top border to not cut off any of the rock bluff particularly because it is nicely rounded into a large ball-like shape. I would also consider moving the left border inward just a little, maybe just stopping short of the pointed top of the tree. On my screen, that cropped format measures about 6.700" X 8.800".
I believe that most people cannot just look at the photo and tell how the borders might be exactly adjusted to improve the composition. The workable method is to go by hunch and actually make the adjusted composition by blocking off part of the image with cardboard, or to do it on the computer. Do this with various hunches, and then just look at them and compare them to choose the best one.
