Awesome stuff. Would love to see concept artists incorporating procedural generated assets in their workflow. Produce 100 samples like this, teach the computer which ones they prefer, produce 100 more, take a few and refine them by hand.
I like to use the ms reading on my stopwatch when I don't have anything else nearby. I'll draw up a few scales like inorganic <---> organic, long <---> short, heavily armed <---> unarmed, and then get a 0-99 ms reading for each by pausing my stopwatch.

The same can be done for character gen, scenario gen, life choices :), etc.
