While Tenshi and Joshua make some good points about pricing and volume, there isn't anything else like this in
SL right now. There are mechs and gynoid skins, but nothing both so feminine and articulated at the same time.
This is unique enough that I think you'd quite safely sell it over L$1000. Sometimes high prices are good because they ensure the buyer that not so many other people will have the same look. This is why some prefab builders charge out the butt for some specific models, because the price keeps too many copies from showing up on the grid, which actually makes the item more attractive to devoted SLers.
Fantastic work!
