This German tank from World War II looks menacing and powerful. It is a green tank with a turret on the top, as well as metal treads around the sides. On the side of the turret is a large white star. To give it an imposing and realistic look, I would use dark green and black shades, plus some metallics for the treads. For the white star, I would use a bright and crisp white, to make it stand out against the green. I might even use a yellow-greenish hue for the lettering on the side of the tank, to really bring it to life. Finally, I would use light gray for the shadows and for the highlights, giving it a more interesting look.
