I did one that was psotworked to look like a watercolour painting here... http://www.renderosity.com/mod/gallery/index.php?image_id=2337087&user_id=681237&member&np

It's rendered in Daz rather than Poser... but still is done as a painting rather than a typical render...

I also have this one which is actually a Poser render that I set up to look more like a painting than an actual realism render...
