Cartoon Elf in a Lighthouse: Whimsical Harbor Glow

A bright, cartoon-style elf with big round eyes and pointy ears, wearing a green tunic, brown belt, and a small pointy hat, standing on the wooden railing inside a seaside lighthouse. The room is cozy with stone walls, a spiral staircase, and a glowing lantern that casts warm amber light on the elf. A desk nearby holds a rolled map, a brass telescope, and a dusty old book. Through the window, a stormy blue sea crashes under gray clouds. Outside the lantern room, a large Fresnel lens, rope, and lighthouse railing frame the scene. The art style should be bold, clean-lined cartoon, flat colors with soft shading, reminiscent of classic 2D animation or vector illustration. Mood: whimsical, adventurous, comforting.
