You made your BW look a lot better than mine. Not my forte. Perhaps it is the quality of light and time of day. My attempts resulted in grayish, muddy looking images and lost detail.
Now on to your image. I like the overall look of the image. The angle of light helps bring out the character of the hills and shows some detail and texture. You also managed to make the differentiation in the colour of the clay hills come out with the mottled grays and whites strewn throughout the hills. I guess that is the bands of lime and other minerals. The rock boulders are well placed in the frame and furrow, and look to me, and always have, like earth giving birth to something new. I like the placement of the furrow because it leads the eye through the image, resting at the boulders, and other furrows and shadow lines and then up to the three tree areas surrounded by dramatic clouds. A nice C-curve sweep.
I have two reservations: One- and it it may just be me and my familiarization with the location- but I can't help seeing this place in anything but the rich red clay colours (so not really a criticism). Two- I find the upper dark area of sky (blue in original colour) a bit distracting, taking away from the sweep. So, I would remove that portion of sky. But that could be my taste, because in the colour version, the dark areas of sky may very well balance nicely, with the dark shadow areas of the rest of the scene.
BTW, what camera you using?
