Modeling and polygon count has to have its purpose.

For clothes, it is best to stay with the same polygon density as the underlying figure.

For props, this is not so easy to Judge. Are the meant to be rendered in close up? Or at a distance?

I'd go for basic modeling, good texturing and displacement/ bump.

Forget normal map as Poser "forgets" specular on normal maps.
