I did not say "exotic" is best..just that when photos are viewed, it is often the exotic which is given accolades over an image which is less foreign to the viewer which might be far superior work of a different sort.  Now, if superior and masterful work and exotic to the eye, that viewer will likely find it pleasing.

I like the idea of the challenge.  This thought did not enter my thoughts but I do like the idea, and for me at the moment would be a challenge, indeed.
