I've bought Levius' reference photo packs from the store, and today he sent out a Renderosity merchant email inviting his past customers to check out his new site. The URL he gave is the same as the one Marque posted. He is probably selling the photo pack in the MP here and also marketing it through his own website, like a lot of the merchants do. It's a really terrific site, too; he has a lot of cool freebies on offer.
