Countless images and imaginings of the same concept and scenery. How, just HOW do you make yours count? I suppose that if you really want to attempt a concept that is not original, the least you can do, it do it better. Do is as good as you can.

Yet again, how do you know if it was good enough?

Maybe if all the world would say "oh yes, you are the nudes in waterfall" photographer, MAYBE that would mean you have done your job properly.

I, whatsoever, tend to think that you can do more than just "importing" a concept. Expand, create, imagine!

By the end of the day, image is just your imagination, reality is rarely revealed.
