There seems to be a contradictory "law" regarding these sorts of character meshes: If it's cute out of the box, it's unlikely that many good renders will come of it. 

I was pretty surprised when the first DAZ adaptation of Girl came out. There was a sudden glut of really bad by-the-numbers sorts of renders, but then, "dressing up Barbie and hitting the render button" is a huge part of this scene ... just not to all of our tastes. It was the same with Koshini ... a very cute character that led to thousands of hideous renders, a tiny minority of good ones.

While it's true that every now and then you see a G4 render that's pretty darned good, that sort of mesh isn't really well-suited to very artistic sorts of art IMO. In general the best you can hope for is a pin-up or otherwise cutesy sort of image that's good enough to make an impression. The irony of course is, as ptrope already stated, that Goosens' original renders with his creation were incredibly charming ... he captured the quintessence of a sort of adorable "girl" we usually associate with images from past iconography, and made her seem current again. Merely having a Poserized facsimile of that original mesh on your HD isn't going to guarantee images of the same allure as Goosens'. As with anything, it takes some work and ideally, a bit of artistic insight and finesse.
