Your question is whether this is "Conceptually Worthwhile".
For a start, it is different from all the other waterfalls we see, the perspective causes a feeling of unease (vertigo? - to me anyhow)
Patricia's picture yesterday was extremely disorientating, so there's nothing wrong with that surely?
To answer your question, the mere fact that it is different from all the others makes the concept worthwhile.
As for the points raised by the other posters, you can always work on those.
Something I will try next time I have the chance - if I can just get over my fear of heights!
