Design an image for use in a business card that evokes a vast, galactic atmosphere. The design should be dark and quiet but convey an overwhelming sense of depth and scale. Use a color palette of deep reds and blacks, incorporating stars and cosmic elements. Focus on organic, fluid shapes reminiscent of swirling galaxies and nebulae, rather than inorganic shapes. The style should capture an epic and transformative feel inspired by dynamic anime aesthetics, without depicting any characters, robots, mechas, or weapons. The image should be abstract and atmospheric, suitable as a professional business card background. --ar 2:1 --no characters, robots, mechas, weapons, text
