Tired field nurse resting on a trunk in a war camp

Medieval times, dark fantasy. Ultra-detailed hyperrealistic image of a young woman with long light reddish wavy hair wearing dark gray late 19th century nurse's uniform, white apron with white ruffled shoulder straps stained with visible drops of blood, white headscarf. She sits tiredly on an old wooden trunk bound with iron strips. Background is slightly blurred showing large canvas military tents and wounded medieval soldiers. Autumn season, overcast weather, gray clouds.
