originals are not high on any list because it doesn't make the site money. if you have no tags you'll never show up any place. and if your talking collections - the site picks those and it's mostly based on sellers. also be sure that when you post someone's sculpture, unless its yours, that you attribute the artist who made it. but yeah, you have no keyword at all. and you sell photos, so there are no originals...
