I think there are good resons why you don't find many great models for free around. 1) its a art form. I don't see many artist going around saying.. hay you want my painting ? you could say it was yours.. 2) a lot of work gose in to them. a LOT. 3) if there is so much work envolved why waist time with something that is not exactly what you want. ei.. make your own custom.

I don't meen to inply there is anything wrong with asking or using free models. Just maybe why there are not many out there..
