Hi guys,
I've been using Makehuman to create ZBrush base meshes lately. It works pretty well, although the mesh needs some work before you can start sculpting (too many triangles, which ZBrush doesn't like, and some overly elongated quads on the arms, mainly, which need subdividing). Having said that, I find it's a huge timesaver to create posed base meshes with the right proportions.
Here's one attempt (environment, clothing, hair and texturing all done in Blender and ZBrush and render in Indigo). Let me know what you think.
