The worst thing about Poser is.... you'll find derivatives of your work - sooner or later.  That is... if you paint Mona Lisa (V3) - you'll see some other folks using it as well... making your picture of V3  worth less or worthless - whichever is less.

The best bet is using rare or unrecognized models that people haven't seen it.  That would give a work more prestige... but if everyone has it... your render is useless and a waste of time.

For this reason, Renderosity continues to thrive on new contents.
