A vertical YouTube Shorts cover, photoreal cinematic fantasy film still with exactly the look of the reference image. A colossal sea monster made of dark rock and barnacled shell rises out of an exploding wall of white water, towering over a small dark longship with a carved beast prow at the bottom of the frame. Grey storm light, spray everywhere, the ship tiny against the monster. At the top, big bold white serif capital letters with a soft dark shadow: "THE SEA ITSELF ATTACKED" on two lines; below it smaller thin serif "THE ABYSS CROWN". No other text. Epic scale, high contrast.
