Summer Touring Challenge Poster

Goal: Create a dramatic vertical Japanese promotional poster for a summer motorcycle touring challenge, blending anime key visual art with event announcement typography.

Canvas: Tall smartphone poster, 9:16 aspect ratio, dark cinematic blue color grading, high contrast, glowing cyan-white typography, rain and water-splash effects.

Layout: At the very top, place a small KusArt logo on the left with thin decorative horizontal lines and diamond endpoints. Center the small header text 「お盆休み企画」, then below it 「OPTION追加」. The dominant title fills the upper third in huge luminous Japanese calligraphy: {argument name="main title" default="夏の一瞬チャレンジ"}. Under the title, add a thin divider line and a two-line subtitle: 「その瞬間にしか出会えない夏を、」 and 「ツーリング作品の見せ場に。」

Main visual: A beautiful anime-style female motorcycle rider with {argument name="hair color" default="long flowing crimson red hair"} and vivid blue eyes rides a glossy black sport touring motorcycle with subtle red and gold trim. She wears a tight black leather racing suit with red accent panels, black gloves, and a confident gentle expression. The motorcycle is angled toward the viewer on a wet mountain road curve, front wheel large in the lower foreground, windshield sparkling with raindrops, tires kicking up water spray.

Environment: Split the sky into a “summer moment” contrast: the left side is bright blue sky with towering white cumulonimbus clouds, distant mountains, and a lake or coastline below; the right side is a sudden dark evening rain shower with dense vertical rain streaks. The road is glossy and reflective, bordered by guardrails and lush green mountain foliage, with sunlight breaking through the rain to create a magical fleeting-summer atmosphere.

Bottom information area: Add exactly 3 glowing cyan outlined text blocks near the bottom. Block 1 is a small pill-shaped label reading 「イラスト・動画どちらもOK」. Block 2 is a large hashtag bar reading {argument name="first hashtag" default="#AIあつあつツーリング動画"}. Block 3 is a second large hashtag bar reading {argument name="second hashtag" default="#AIあつあつツーリングイラスト"}. At the very bottom, display the deadline in large bright numerals and Japanese text: {argument name="deadline text" default="8/16 23:59まで"}, with thin decorative lines and diamond endpoints.

Visual style: Premium anime illustration, highly detailed motorcycle rendering, glossy wet surfaces, cinematic lighting, electric blue glow, crisp Japanese typography, rain particles, water droplets, dramatic poster composition, polished social media campaign design.

Constraints: Keep all text legible and in the specified Japanese wording. Use exactly one rider, one motorcycle, three bottom text blocks, and one deadline line. Do not add extra logos, extra hashtags, QR codes, or watermarks beyond the small KusArt logo.
