3D skin close-up for extreme macro?

  • Hi, everybody!
    I'm looking for a 3D model of human skin close-up (for some serious macro renders). something like this:
    any ideas? I've purchased Silo, so I guess once I'll learn the basics of modeling it shouldn't be too difficult to create this, but if any of you bumped into something for sale already done, I'd love to know.

    thanks :)
