Yeah, it does seem like its own original model, so that's pretty cool.

Also, while we're unashamedly pointing out 3D models' cleavage, ummm, Salem's boobs seem more defined in Volume 6. In Volume 4 (and I think Volume 5?), she just had a line down the middle in the boob window of her dress, much like Emerald's Poser model had, but in the Volume 6 trailer, there are actual defined lines for her boobs visible in the boob window.
