Evolved images are something we do, I don't think they happen anywhere else, but the logic is very simple. If you commission three images at $100+ each (not nessesarily all together) you can get a third free and a signed print version of your favorite artist. The route to getting an EVO image is a simple one.
*Due to the nature and local laws we cannot send hentai out through the mail. You're welcome to submit a hentai as your free image, but it will have to be a digital version. We'll still sign it of course. But this offer is only open to Pin-up requests.
