Darth Vader stands atop a balcony, his arms crossed and his black cape billowing in the breeze. He wears a helmet that is slightly tilted to the side, revealing his dark hair, a pale scar running down his stony face. His expression is serious, perhaps even menacing. For this image, you might want to color Vader in shades of black and grey, to emphasize his ominous presence. Make sure to use touches of white to bring out the details of the face and hair. If you would like to make Vader really stand out, you could add a hint of red to his cape. Be sure to also use some muted blues and grays for the balcony and the sky to make Vader come alive against the background.
