Gouache-Reisetagebuch Stilübertragung

Use the reference photo as the exact blueprint. Preserve the composition, camera angle, perspective, framing, subject poses, clothing, lighting direction, and background layout exactly as shown, keeping every element in its original position and scale. Transform the rendering into a vibrant [hand-painted travel illustration with gouache and watercolor textures], featuring visible brushstrokes, colorful ink outlines, soft shading, and a whimsical travel journal aesthetic. Add playful hand-drawn doodles strictly within empty sky and border areas, such as a stylized sun, clouds, hearts, sparkles, stars, and colorful decorative marks. The final result must look like the reference photo faithfully redrawn as a charming travel sketchbook illustration.
