The materials look nice and the render is sharp but apart from that I don't find much more to comment about. It's not clear to me what you wanted to achieve here, what's the concept.

One thing: if you apply x-ray materials to a Poser character, you must be aware that they immediately become non realistic because you reveal their inside, which is not even remotely similar to a real human. So, if you wanted to achieve some realism, you could have put a skeleton inside the bodies, for example.
