Old sailor faces sea monster on moonlit dock

A film noir style image with color of a tough old sailor standing on the end of a long, rickety dock on a moonlit night. Coming in from the sea is a horrible Cthulhu. Others on the docks are running away in terror but the sailor is standing his ground while the Cthulhu approaches. Gritty realism defines the decaying facade and the overgrown, untamed landscape. Volumetric lighting filters through the dust motes, casting long, eerie shadows.
