Thanks for posting the rest of the information.
1. Yes. There seems to be too much in the photo and therefore, no real center of interest. (-1) This is a shot that could have been more impactful (-1) with a wide angle lens. You could have then placed the foreground, which is very interesting with its curves and textures, as the main subject and the sky and mountains could have been framing your foreground, and the wider angle would have allowed you to include more sky. (-1 for creativity). Your composition and color balance are excellent, as well as lighting and exposure.
2. I don't think converting to black and white will do much for the photo. You might lose some detail and it might get more cluttered.
There's a lot of potential here if you go back . . . pack a good wide angle lens when you do go! Your photo earned 9 out 12. (9/12)
Actually a nice photo but IMHO would have been a 12 if you had a wider angle.
