A little while ago i found a drawing by an artist Mike Sekowski,it is of a world war robot /Ashley Wood type bot finding a hidden sniper and finally putting and end to his/her life,i really like this idea and asked him if it would be ok if i could make it into a diorama and he kindly said yes.
I put a hound on the shield and cloth parts as a homage to his pet dog and put his blog name for the division the bot is in/from.
You can check out his blog and images here:
