I like the colour treatment, the blur in the waterfall and the way that the cliff really stands out from the rest of the frame, but feel that it could do without the people on the clifftop.
Sepia works well for this subject and the comp is fine, except the upper right corner seems unnecessary. IMO the highest point should be the "lover's leap" location. Great shot. All the best.
I like the 'fantasy' appearance of this photo. I'm only slightly pulled back to reality by the right hand side which feels too cluttered at the top. Well processed.
