The Black Widow towers ominously from a rooftop, looking out over the city with a steely gaze. Her jet-black leather suit fits like a glove, glinting in the light of the setting sun. A red hourglass symbol is positioned proudly upon her stern chest, radiating with a fiery power. Her fiery red hair swishes delicately in the wind, creating an aura of undeniable strength and ferocity.
Coloring this image could involve blacks and greys to emphasize the sleek and dominating leather suit, as well as brighter reds to highlight the symbol on the chest and the hair. For the background, purples and blues could be used to create a dramatic result as the Black Widow stands against the city skyline. Yellows and oranges could be used to emphasize the sunset, giving the image an unmissable intensity.
