Good overall layout and composition. Construction looks good too..
The KIA shows the reason it's realy hard to depict casualties in plastic. He is arched above trhe ground he's laying on. A dead body is initially in an absolutely relaxed, if contorted position. . At death, all muscle tone is gone since nerves are no longer working so everything slumps down with gravity. Most figuresa are sculpted with gravity pulling from head to toe. A dead body has gravity working (in this caes) from front to back. Even in rigor, the body remaion in the position it died in. As decomposition sets in, skin tissue will begin to dry and contort al the features. As he body decomposes, there may be bloating as gas builds up in the body cavity. This is slower in the cold, howwever. There should be no space between him and the ground. Sorry to be so graphic, but if you look up some Civil War and Indian war photos, you will see the effeects I'm describing. It ain't pretty. Even a freash, intact corpse is quite emotionally disturbing.
IMHO, you'd have a stronger composition without him there.
