Here is the picture I'm working on for my sister (it's my skydrive folder, so it's being updated as the render progresses--nifty trick that).

The concept was "a manaborg* with some sort of exotic pet.  Make sure she's wearing some sort of adventurers clothing."  As my sister is a big fantasy fan, I went with that.  If that's something "useful" I'll be happy to let you know when the render is done if you want to use it here.

* magical cyborg for anyone who was unclear
