"I SURVIVED 100 DAYS" 是一张生存挑战的 YouTube 缩略图，采用高对比风格。带粗黑描边的巨大黄色字母位于夜晚森林中的篝火和木棚上方，右侧三分之一留成纯暗色，用来放人脸。可以换成你自己的标题，再把你的照片放进空白处。

Create a finished YouTube thumbnail in 16:9. Use a high-contrast survival-challenge scene: a rough timber shelter and a small bright campfire in a dense wilderness at night, with dark pine silhouettes and a few ember sparks, concentrated in the left two-thirds. Keep the entire rightmost third (x=67–100%) plain, uninterrupted near-black charcoal, with no props, text, patterns, or bright details; reserve it as clean space for a face to be added later. On the left, set the exact headline in two oversized stacked lines: “I SURVIVED” and “100 DAYS”. Make the lettering fill most of the left half, with bold uppercase condensed block forms, tight spacing, straight edges, and sturdy proportions. Render the letters in saturated bright yellow with a very thick, crisp black outline and a small hard-edged black drop shadow. Keep every word fully legible against the scene; do not add any other words, numbers, logos, or badges. Compose the headline in the upper and middle left, with the shelter and campfire visible as a supporting survival subject in the lower center-left, partially behind the lettering but not obscuring it. Use sharp visual separation between the detailed wilderness scene and the empty dark face zone. Palette: bright yellow, near-black, deep forest green, and restrained campfire orange. Thumbnail-scale readability, strong edge contrast, cinematic directional firelight, hard rim highlights on the shelter, crisp shadows, detailed but uncluttered scene, polished commercial key art. No watermark.
