"Do not generate any duplicated or mirrored facial features, including but not limited to duplicate eyes, noses, mouths, or any part of the face. Ensure each facial feature is unique and does not appear more than once. Avoid any futuristic or science fiction elements, such as advanced technology, spaceships, robots, or futuristic architecture. Do not create concepts that imply an advanced future society or technology that doesn’t exist in the present. Additionally, do not generate repetitive or copied designs, patterns, or shapes. Focus only on original, single-instance, non-repetitive creations, without any redundant visual or conceptual elements. The goal is to produce a unique and original design, free from duplication and futuristic influences."
