Here is an Armadillo fetus, part of a set of three I'm currently doing in my sparetime!

Workflow is generally Sculpt from Zbrush primitive, use dynamesh to get the rough forms and zremesh for quick topo. Continue the sculpt to final and then decimate the mesh for rendering. 
Create a simple lighting setup for this senario and then comp up in Photoshop. 

Enjoy the images and don't hesitate to drop any questions, Like or comment below.
