Retro Christmas Postcard of Miami

Round retro-style Christmas postcard illustration of Miami, Florida, painted with warm nostalgic tones. A decorated palm tree sparkles with holiday lights near the beach, with Art Deco pastel buildings of South Beach glowing at dusk. Santa hat on a lifeguard tower, holiday wreaths on balconies. Tropical holiday cheer, cozy yet sunny feel, painterly brushwork with vintage texture. All elements contained within a perfect circle. No text, no border. White or transparent background.
