Cute Spooky Halloween Twilight Banner

Halloween banner, wide horizontal 3:1, two-panel layout, flat vector cartoon.

[Typography] rounded bold display headline with orange gradient and dark outline, a hand-drawn ribbon banner beneath, small caps for the English tagline. [Subject] a big cream full moon behind a cheerful ghost in a witch hat, a second small ghost peeking out, a black cat with a yellow collar, a pile of grinning jack-o'-lanterns, castle and leafless tree silhouettes on the horizon, bats. [Lighting & Mood] soft dusk glow, cute and welcoming. [Details] layered hill silhouettes, picket fence, drifting clouds, flat grain-free shading.
