Sci-fi and fantasy are the two biggest items I am looking for.  The Dystopia buildings over at DAZ are great, but I want more of them, or more like close-up versions for a street level scene.  They came out with one corner building, but who know when there will be more.  I like the room that they made, but again, only one.  I'd love a sci-fi/modern looking room with a balcony and opening sliding windows. 

I love old, broken, scary buildings with long hallways.  There was a thread on the Cinema 4D forum about Deep Down Below (http://www.renderosity.com/mod/contest/index.php?contest_id=931)  that would be really great types of stuff for Vue. 

Biggest disappointments are sharp, un-realistic edges on objects.  Don't use un-altered primitives to build the model - edges should have just a bit of rounding. 

Also, just because it a sci-fi scene, don't make every texture have a million greeble parts and dark and grungy like coflek-gnorg's products here at Renderosity.  I have bought some of his products, but I feel like the doors are much to heavy and out of scale to the rest of the buildings...
