Create a vibrant childlike crayon-style 9:16 vertical illustration titled [City Name] Travel Journal. Make it look like a curious child drew a fun travel diary page with colorful crayons. Use a soft warm pale background, cheerful red, blue, green, yellow, and other bright colors, and a cozy playful travel mood. In the center, draw a winding Z-shaped travel route map with arrows and dotted lines connecting recommended stops for [Trip Days]. If the trip length is not clear, treat it as a one-day highlight itinerary. Generate city-relevant stops automatically: first stop, second stop, third stop, and a final stop featuring local food or a souvenir with a warm closing note. Around the route, add cute childlike doodles: small travel characters holding local snacks or wearing backpacks, chibi hand-drawn landmark icons for [City Name], funny little direction signs, sticker-like phrases about travel memories and food adventures, local food icons, hearts, stars, arrows, and innocent exclamations such as wanting to visit again. Use a crayon and children's hand-drawn travel journal style, bright warm palette, full but friendly composition, exploration energy, and cute handwritten lettering. Keep all text short, decorative, and easy to read. Do not include real brand logos, source watermarks, unrelated city names, or long dense text blocks. Output a high-quality 9:16 image suitable for GPT Image 2.
