Chennai Watercolor Travel Poster

Goal: Create a richly detailed vertical watercolor travel poster for {argument name="city name" default="Chennai"}, celebrating South Indian coastal culture with a busy heritage street scene and an illustrated guide strip at the bottom. Canvas: Tall vertical poster, approximately 2:3 aspect ratio, textured cream paper with watercolor washes, ink outlines, hand-lettered typography, warm sunlight, saturated temple colors, and a nostalgic travel-journal feel. Top title area: Large navy-blue brush-script headline reading {argument name="headline text" default="Chennai"}. Under it, add a small uppercase serif subtitle reading {argument name="subtitle text" default="INDIA'S COASTAL SOUL"}. Below that, a handwritten line reads {argument name="tagline" default="Where temples, tide and turmeric meet"}. Near the upper right, place a round vintage passport-stamp graphic reading "CHENNAI TAMIL NADU" around a small auto-rickshaw icon, plus a small vertical red Tamil-style city mark beside the title. Main illustration: Depict a bustling Chennai street in Mylapore with an ornate, multicolored Dravidian temple gopuram rising in the middle distance, surrounded by dense shopfronts, street signs, overhead wires, scooters, pedestrians, and soft blue sky. A huge banyan tree dominates the upper-right corner, with twisting branches, aerial roots, and bright green leaves casting dappled shade. In the foreground left, show a flower seller in a red-orange sari seated beside large baskets of white jasmine garlands and pink lotus flowers. In the center foreground, include one yellow-and-black auto-rickshaw facing the viewer on the road. In the midground, show one woman in a red silk sari walking, and a group of schoolchildren in uniforms crossing the street. In the foreground right, show a coconut water and filter coffee stall with green coconuts, brass vessels, and steaming coffee equipment. Visible signs and labels: Include exactly 9 prominent sign or text elements in the main street scene: 1) blue sign "MYLAPORE", 2) brown sign "KAPALEESHWARAR TEMPLE", 3) yellow Tamil-style street sign, 4) shop sign "SRI RANGA SILKS", 5) black chalkboard "MALLI POO FRESH JASMINE", 6) green board "TENDER COCONUT WATER", 7) black chalkboard "FILTER COFFEE STRONG & FRESH", 8) brown Tamil-style stall sign near the temple niche, 9) the circular "CHENNAI TAMIL NADU" stamp. Use Tamil-inspired lettering where appropriate, but keep the poster legible and decorative. Bottom guide strip: Add a cream scrapbook-style horizontal panel across the bottom, separated from the street scene. It contains exactly 5 vertical sections: 1) an intro column titled "Chennai" with the handwritten text "A city where every street has a story." and four icon captions: "Ancient temples", "Filter coffee culture", "Marina Beach breeze", "Heritage rail hub"; 2) a small watercolor vignette of fishing boats at sunset labeled "Marina Beach"; 3) a small watercolor vignette of a temple tank and gopuram reflection labeled "Mylapore Tank"; 4) a small watercolor vignette of a busy silk-shopping street with a visible "POTHYS" storefront labeled "T. Nagar"; 5) a pale watercolor map of Tamil Nadu with a red pin labeled "Chennai" and the handwritten note "Between heritage and horizon, Chennai stays with you." Add a small red Tamil-style stamp at the lower right of the strip. Style constraints: Make it look hand-painted rather than photorealistic, with fine ink details, splashes of blue watercolor in the sky, warm ochre street tones, lively market colors, and authentic Chennai atmosphere. Keep the composition dense but readable, avoid modern corporate design, avoid blank areas, and do not add extra panels or additional major signs beyond the specified counts.
