AI Prompt for Retro Architecture Illustration with Vintage Cars and Waterfront Cityscape

"A vintage travel poster illustration for {argument name="destination name" default="MALTA"}, with the subtitle {argument name="tagline" default="MEDITERRANEAN PARADISE"} centered near the top. The composition is a sunlit Mediterranean coastal cityscape viewed from a curving seaside road in the foreground, painted in a richly textured retro poster style with warm cream stone architecture, saturated turquoise-blue sea, and a bright azure sky with soft white clouds. On the left, a hillside of tightly packed historic limestone buildings rises above the waterfront, including colorful enclosed wooden balconies, a large domed church with a reddish terracotta roof, and a slender church spire. In the foreground on the road, place a classic mid-century white sedan seen from the rear three-quarter angle, driving along the curve, with a dark license plate reading {argument name="license plate text" default="MTA 1964"}. A low stone seawall runs along the right edge of the road beside the harbor. In the bay, include exactly 4 boats: 2 colorful Maltese luzzu fishing boats in the near and mid water, plus 2 smaller distant boats farther back. Add exactly 4 white seagulls gliding across the sky above the water. Frame the scene with lush flowering bougainvillea branches in vivid magenta-pink arching across the upper right and lower right corners, and leafy tree branches along the upper left edge; include a spiky agave plant in the lower left foreground. The distant shoreline across the bay should show a pale sunlit city stretching along the horizon. Use a nostalgic 1950s–1960s tourism poster aesthetic, painterly brushwork, crisp composition, romantic travel mood, and elegant typography with the main title in large cream serif capitals and the subtitle in smaller dark sans-serif capitals."
