Generate a photorealistic image of a highly detailed and perfectly crafted latte art design. The foam art should intricately represent [SPECIFIC SUBJECT, e.g., 'a majestic lion's head', 'a delicate floral pattern', 'a company logo']. Present this art within a clean, minimalist white ceramic coffee cup. The cup should be resting on a polished white marble surface, featuring subtle grey veining. Employ a slightly overhead, close-up camera angle, utilizing soft, diffused natural lighting to highlight the texture and crispness of the foam. The overall aesthetic should be that of high-end, professional product photography with a shallow depth of field.
