A visually striking Instagram post design featuring a minimalist aesthetic. Imagine a close-up shot of a single, vibrant flower against a stark white background, its petals perfectly arranged. The lighting is soft and diffused, creating a sense of serenity. The color palette is predominantly white, with a pop of color from the flower (perhaps a deep magenta or a sunny yellow). Text overlayed is clean and modern, using a sans-serif font. This is rendered as a hyperrealistic digital photograph, detailed to the point where you can almost feel the delicate texture of the petals. The image should exude an air of sophisticated simplicity, perfect for capturing attention in a crowded feed.
