I dug out Poser5 (free) and ran with the wolves.  GeoControl terrain.  Photo sky blended with bryce sky.

I've experimented with myriads of skys, atmospherics, soft shadows, etc and it still comes across too sterile for my liking.   I like the scene but I can't seem to make it art, if you know what I mean.  Believeable... softer... whatever...Suggestions? 

I'm taking a chance but I'm going to cross post this in the critique forum also to solicit no brycers views.
