I didn't notice anything wrong with it the first time. It's very nice but now it is crooked. Did you burn any of the waterfall? I have had to burn waterfalls before to give extra detail to the water. I think you might have another rather nice photo here as a crop of this image. The lower fall would look nice just on its own. With the MF negative you may well be able to do that if you wanted.
I enjoy scanning. Far better visually to scan negs and post-process than to scan prints. No dust specks for me with roll film or 35, only with sheet film due to dust in changing bag. This is a lovely photo...especially like the combination of very dark and the mottled light on upper vegetation.
