The specimen below is similar to one that I had drawn for my parents for Christmas. As I forgot to scan it, and, you know, it's a present for my parents :), I can't exactly take it back. So, I tried to redraw him from memory. It didn't work out very well, I think I was little enthusiastic with the dark shading, and isn't as delicate as I like to draw, but he's a specimen never-the-less...
Here is Specimen #18b (fetal)
