Create a vibrant hand-drawn editorial travel poster combining the visual language of Seoul and Tokyo, in a nostalgic retro Asian travel-illustration style. A stylish young East Asian woman walks confidently across a wide urban crosswalk in the center foreground, wearing a contemporary dark oversized outfit, loose trousers, sneakers, and a crossbody bag. The street stretches deep into the background with strong symmetrical perspective, surrounded by dense modern buildings, pedestrians, storefronts, colorful vertical signs, overhead utility wires, street lamps, taxis, and lively city details. Blend Seoul and Tokyo visual elements naturally: Korean Hangul and Japanese signage, a yellow Seoul-style taxi mixed with Japanese urban vehicles, while placing a recognizable Seoul Namsan Tower and Tokyo Tower rising in the distant skyline as complementary landmarks. Use a warm cream paper background with muted red, blue, orange, teal, yellow, and black accents. Strong expressive black ink outlines, rough hand-drawn brushwork, delicate watercolor fills, vintage paper grain, imperfect ink edges, subtle print texture, nostalgic travel-poster atmosphere, charming graphic-novel aesthetic, cinematic depth, highly detailed architecture and characters. Add bold hand-painted typography at the top reading "SEOUL × TOKYO", with a small handwritten subtitle "Discover the hidden pulse of the city." Elegant editorial composition, balanced layout, authentic illustrated travel-poster feel, vertical 4:5 format, high detail.
