I much prefer the new B+W to the previous version, in which the color didn't seem to me to add anything. This one is nice.
The new second image is more interesting to me than the previous second image. The color works better than in the very first image, and the composition feels more interesting than in the centered rock. I'm not certain that the color adds. You might try a B+W of thus, but I don't guarantee it will work better.
But the new B+W is very nice, and the somber rock is matched very well by the glowing light on the horizon.
