Crouching Daphne, Hidden Velma by hojojitsu.deviantart.com/ Please note that some of their work is NSFW (it's behind DA's mature content filter so will be invisible if you view the gallery not logged in).
Were these versions of Daphne and Velma created in DAZ Studio or Poser, or what program? I'd be quite interested in creating a 3D version of Daphne.
I did purchase the Millennium Dog, which would make a great Scooby. As for the teens, the best I could do by this point was Velma.
