The document describes the stages of developing concept art for a character. It started with designing the character's body armor and making refinements. Background elements like a brick wall, fence, and buildings were then added to make the setting look more atmospheric. Colors and lighting were adjusted to give a dull, military-like and creepy feel. Over multiple stages, more details were added like bullet holes, debris on the walls, and zombie hordes in the distance. Different zombie designs and destruction elements were incorporated to finalize the character concept art.
