Front and center on the card, feature a flat, vector-style illustration of the TARDIS. Its iconic blue hue should be crisp and vibrant, with precise, clean lines marking the paneling of the police box. The words "POLICE PUBLIC CALL BOX" should be neatly inscribed in a bold, sans-serif font across the top, capturing that quintessential Doctor Who detail.

Standing just outside the TARDIS, the 12th Doctor, Peter Capaldi, is depicted with distinctive vector-style simplicity. His gray hair is depicted in a stylized, geometric fashion with angular lines. He’s wearing his signature outfit: a dark navy Crombie coat with a red lining that could be exaggerated slightly for flair, and his classic black trousers. His white shirt and black waistcoat should be flat and crisp, contrasting sharply against the coat. A pair of subtle, round sunglasses sit perched on his face, adding a layer of cool.

The background is an abstracted version of a starry night sky, using deep indigo and purples with minimalistic white dots scattered across to represent stars. Subtle, flat planetary shapes in soft pastels of pink, yellow, and teal hover in the backdrop, suggesting a cosmic setting without overpowering the central figures.

The ground upon which the Doctor stands is a simple flat plane in a muted charcoal shade, offering a foundation that highlights the standing figures without drawing focus away from the TARDIS and Doctor.

Finally, delicate heart shapes in various sizes float around the scene, rendered in clean, vector lines, and filled with shades of red and pink. These hearts subtly nod to the Valentine's theme, bringing a playful twist to the otherwise sci-fi inspired illustration.

The composition should be balanced and harmonious, with an emphasis on flat shapes and crisp lines, inspired by the clean, bold styles of artists like Malika Favre and Patrick Seymour.

Generated with these themes: TARDIS with the 12th doctor standing outside.
