Nicely done. No make that very nicely done.
The composition works for many reasons. The horizon is in the top third which gives the feeling of great distance and depth. Most people see from left to right and top to bottom. The cliff draws us in naturally and effectively. You have a strong but natural colour shift from one side of the shot to the other.
I have found it very helpful to become acquainted with the Renaissance masters who looked deeply into composition as they developed their painting styles. The same rules and techniques they developed can be transferred to photography.
