In the past I've uploaded several kinds of images (not just on DA, but also on Renderosity, Flickr and 3DCommune): from portraits to nature photography to oekaki drawings to manipulated photographs to filter-generated imagery to 3D renders.
My question to you is simple: What do you like the most, and what would you mostly like to see to appear here?
Would there also be stuff you'd like to see available in prints?
