*However, just because someone models something from scratch, then uses it to make art does not necessarily mean they are a better artist than someone who uses Poser models for a base.

*Excellent point, and if I might add, Setting up the initial pose says a lot in any given scene, i've seen many failed attempts, but i've also seen many genuine results like the one in the first link.
 
If one takes a long time working from scratch, then setting a realistic pose can also take time. Just one little finger awkwardly placed can be the difference between perfection and "thats just another poser render".
