Original idea you came up with, but now it is nonsolutely in demand as I think. Paying for the art with tokens is very convenient and reasonable, you still need to make some rewards for uploading art pictures. I think you need create bot which will check pictures for originality and which will automatically transfer awards.
Hello Redanim,
We have good plans to market the platform. We will start approaching the photographers once we have our beta release up. There will be contest for the photographers to take part in. Most of these contest rewards will be tokens. More activities are lined up for the same to promote the platform.
