Thanks, everyone, for the comments! The skull is a Fusilier piece. In fact, the Fusilier offers an extensive line of spare parts and bits and pieces that really help dress up any Great War scene.
The German is only slightly changed from the stock kit. I repositioned his right arm, substituted a hand holding a grenade instead of the kit-supplied hand holding a rifle, and swapped heads. The British soldier in the mud is made up of pieces from my spare parts box. Ken Thomas produces some great bases that really makes it easy to incorporate the groundwork right into them.
Gary, as for staging, I put a lot of thought into that aspect of my figure modeling. I'm sure it comes from my career as a theater instructor and director!
