Nice greenery. You were already clicking at 18mm. So can't ask for a wider scene. If somehow you could have included more of the foreground at the left, to make it appear as a part of pattern of curves along with the green hill in the middle, then it would have been great. Also, including more of the distant blue hills would have been good.

In this case, the foreground ie. the left side greenery is much brighter than the hill in the middle. Typically, one needs to decide the composition after considering the difference in tonalities. With a graduated Neutral density filter one can experiment. If possible, go down the cliff to get a different perspective, but be safe.
