"Do Not Watch" は、ホラーチャンネル向けの、血がしたたる風のYouTubeサムネイルです。かすれてしたたる赤い文字の2語が暗い霧の上で中央を埋め、その下に字間を広げた小さなチャンネル名の行があり、右下は空けてあります。自分のフックとチャンネル名に差し替えて作り直せます。

Create a 16:9 YouTube horror-channel thumbnail, optimized for instant readability at small feed size. Pure black background with a narrow cold charcoal fog band across the lower third. Center the exact headline "DO NOT WATCH" in two stacked lines, occupying most of the frame. Design custom hand-applied horror lettering: broad, uneven crimson strokes as if smeared with a blood-covered finger; pressure-driven variable stroke widths, irregular edges with dried near-black crust, dense wet accumulations at inner corners, slight gaps and opacity variation. Thick blood gathers beneath selected letters and falls in a few short gravity-pulled drips, each ending in a rounded tear-shaped drop with visible surface tension; deep crimson #B00012 highlights grade to near-black brown #260004 in pooled areas. Add a restrained cold red rim light from screen-right to create wet specular streaks across the convex blood surfaces. Behind the headline, barely visible in the blackness, place a cropped human face with hollow shadowed eye sockets and one small pale reflective eye at upper right; it must remain secondary and partly obscured by the letters. At the bottom center, set the exact channel name "NIGHTMARE FUEL" in small, widely tracked condensed uppercase bone-gray lettering, clean and sharply legible. High contrast, uncluttered composition, no extra words, no logos, no icons, no decorative borders, no warm colors.
