"I SURVIVED 100 DAYS" は、サバイバル企画の動画向けの、コントラストの強いYouTubeサムネイルです。太い黒縁の巨大な黄色い文字が左上を埋め、その下に短い一行があり、嵐の森の焚き火と木の小屋が背景です。自分の企画タイトルと場面に差し替えて作り直せます。

Create a finished 16:9 YouTube thumbnail for a 100-day survival challenge. Use a high-contrast, cinematic survival scene: a battered timber lean-to, a small smoking campfire, wet rocks and dense wilderness under a storm-dark sky, concentrated in the left and lower-center of the frame. No person or face. Reserve the entire rightmost 30% as relatively uncluttered dark teal sky and softly blurred foliage, with no text or focal objects, leaving clear space for the creator to add their face later. On the left, set the exact headline “I SURVIVED 100 DAYS” in two stacked lines: “I SURVIVED” above “100 DAYS”. Make the lettering enormous, heavy, condensed, uppercase, bright saturated yellow, with a thick clean black outline and a small hard-edged black drop shadow. Keep every letter fully inside the frame and legible at small thumbnail size. Add the smaller exact supporting line “NO FOOD. NO SHELTER.” beneath the headline in compact bold white uppercase lettering with a dark outline. Render no other words, labels, logos, or watermarks. Use a custom, tightly controlled thumbnail composition: text owns the left two-thirds; the battered shelter and fire sit low beneath the title; the right third stays open for a face overlay. Use crisp silhouettes, warm orange firelight against cool stormy teal shadows, strong local contrast, sharp foreground details, and a subtle darkened edge behind the type for readability. Photorealistic 3D scene rendering, dramatic directional lighting, bright fire rim light, ray-traced wet-surface reflections, restrained smoke, clean separation between text and scene.
