Design a social media poster featuring a sleek and minimalist aesthetic. The background should be a soft gradient, transitioning from a light pastel color to a darker shade. Center the text “Thanks promeai, Please follow me for stunning art” in a bold, modern sans-serif font. Use a high-contrast color for the text, such as deep navy or charcoal, to ensure it stands out against the gradient background. Incorporate a subtle geometric pattern or abstract shape behind the text to add depth. The overall look should be clean, with ample white space to keep the focus on the message.
