Love the shape of the models rear.

But you might leave out the motorcycle since it looks considerably less realistic than everything else.

This tutorial should be of some help:

As for the file types:
A PZ3 file holds an entire scene (props, lighting, figures, etc)
PZ2 holds a pose information
CR2 holds informationa about a figure
CM2 holds camera info
FC2 holds facial expressions and can also contain morphs settings for creating a specific face.
HR2 are for hair props
HD2 hold poses that just effect the hands
LT2 holds lighting info
PP2 are for props

Very good. That is the best I have seen yet.
You ought to put a MOR pose for that on the Marketplace.

And where did you manage to find a bearded texture for V3, or is that something you created?

Those the V3 Male pack faces help, but they are still too effeminate looking. The brow ridges seem too small, lips too full, and noses too pert and rounded to give a "rugged" appearance. Granted, I have been able to fix a lot of this with the morphs, but I have never hit on anything that looks right. I was hoping someone out there had more success with this than me.
