Prompt tạo poster du lịch Hà Nội phong cách tiny planet rực rỡ

Create image Vertical 4:5 vibrant travel poster, playful fisheye "tiny planet" composition, warm sunset sky blending magenta, orange and deep blue. COMPOSITION — three clearly separated horizontal zones, all fully inside the frame: UPPER THIRD: white brush-script "Khám phá" with a tiny plane, then a huge yellow brush headline "HÀ NỘI"; a white sub-band "ĐI MỘT LẦN - YÊU CẢ ĐỜI"; a small icon row "CHỢ ĐÊM PHỐ CỔ", "ĐI BỘ HỒ GƯƠM", "ẨM THỰC VEN ĐƯỜNG". MIDDLE: two stylish young Vietnamese friends (a guy and a girl) in trendy streetwear sitting and crouching on a curved miniature grassy globe, laughing, one reaching a hand toward camera; the tiny planet wraps with palm trees, lantern-lit streets, a river and a lantern bridge; around the horizon rise central-Hanoi landmarks — the The Huc Bridge, the illuminated pedestrian street around Ho Guom Lake, Tran Quoc Pagoda, Ho Chi Minh Mausoleum, and Long Bien Bridge each displayed a small Vietnamese flag.; a small airplane with a dotted trail top-left; scattered props: vintage film camera, red map pin, small suitcase with stickers, conical hat. LOWER THIRD: a yellow brush banner "HÀ NỘI NGÀN NĂM VĂN HIẾN" with a handwritten line "Chạm một lần - Nhớ một đời!". IMPORTANT — SAFE MARGINS: compose the whole layout to fit completely within the canvas with generous padding on all four sides; do NOT crop or cut off the top headline, the small icon row, or the bottom banner; every top and bottom element must be fully visible with empty margin to the edge; nothing bleeds off the frame. Saturated, fun, high-detail.
