A young girl in a futuristic sci-fi suit, portrayed in the style of a vintage Soviet poster, stands confidently with a hammer and sickle subtly integrated into the background design. Behind her, a colossal mech looms under a clear, sunny sky, casting a dramatic shadow reminiscent of classic anime and manga graphics. The artwork is rich in dark colors with exceptionally high detail, capturing the essence of offset printing. The poster, designed in 8K resolution with a vertical aspect ratio, uses a CMYK color palette. The girl's expression is joyful, illuminated by natural lighting that enhances the overall vibrant yet nostalgic atmosphere.
