Rough, gritty anime style with jittery, trembling ink lines and messy, hand-drawn aesthetics. Foreground right third: the weathered, rust-eaten edge of an old fishing vessel deck, with a lone sailor leaning over the railing, hunched and small, staring in awe and terror. Left two-thirds: a colossal cosmic entity rising from the ocean — a massive cephalopod horror in the style of Cthulhu, with enormous writhing tentacles erupting from churning black water, a bulbous alien head with countless eyes, and a body so vast it dwarfs the boat entirely, rendered as a looming blurred silhouette with only glimpses of slimy textured flesh visible through the sea spray. The scale must be overwhelming — the creature's base tentacles alone are wider than the entire ship. The ocean is chaos: violent waves rendered in frantic, sketchy ink strokes. Color palette: deep prussian blue, sickly green-black, and pale moonlight whites, high contrast, no clean gradients, raw and expressive energy.
