Travel poster generation prompt depicting Istanbul and Paris in photographs and watercolors

A composite vertical image featuring a photograph of a bustling Istanbul street scene leading towards the Hagia Sophia and Blue Mosque at the top, while a photograph of the Parisian skyline with the Eiffel Tower and Notre Dame sits below it. Each photographic section is paired with a corresponding miniature watercolor painting below it, centered on textured paper, depicting the same city view. Handwritten-style text labels each watercolor painting: "Istanbul" in a flowing script font for the first and "Eiffel tower/Paris" in a clean, handwritten font for the second. The entire piece is presented as a two-panel, vertical layout, with a clean break between the Istanbul and Paris sections.
