Girl illustration poster urban street high-end

Create a high-end editorial-style illustrated travel poster for , with the main body made of 8 huge vertical uppercase letters spelling out “ISTANBUL” on a wide cream-colored canvas. Treat each letter as a vertical window filled with detailed Istanbul scenery: 1) I shows the Maiden's Tower on the Bosphorus, the Turkish flag, and a ferry; 2) S shows hillside waterfront neighborhoods, domes, minarets, clouds, and flying birds; 3) T shows the Galata Tower above a narrow street, with a red retro tram in the foreground; 4) A shows the Bosphorus, ferries, sailboats, a bridge, and the distant city skyline; 5) N shows Hagia Sophia and cascading mosque domes in warm peach and stone tones; 6) B shows the Bosphorus Bridge, water, ferries, and a waterfront palace; 7) U shows steep historic streets, colorful stacked houses, greenery, and a large tree; 8) L shows the Ortaköy Mosque on the waterfront, with two minarets and flying seagulls. Above the title, add a minimalist thin skyline strip containing 13 small illustrated elements from left to right: a tree, a small domed pavilion, a teal car, a red tram, a distant city tower, a ferry, a suspension bridge, the Maiden's Tower, another teal car, a large mosque with multiple minarets, a peach sun, a round green tree, and finally a mosque minaret. The overall style is a refined mid-century travel poster, using a clean vector illustration style, with a color palette of soft teal blue, sea green, gray peach, terracotta, warm cream, accented with charcoal gray lines; the composition is geometric, with delicate paper texture, elegant negative space, dotted with tiny flying birds and clouds, rejecting photorealistic photography style, and containing no extra text besides the city name.
