Retro Christmas Greeting Poster with Playful Tree

Professional Christmas greeting poster, vertical, retro halftone print finish. [Colors] Sea green and mint (#2E8B74, #A8DCC8) over a pale ice-blue field (#DCEBF2), with tomato red and butter yellow accents. [Layout] Centred stack: an oversized headline across the top, an italic secondary line under it, a vertical tagline hugging the left edge, and a cartoon tree character filling the lower two thirds. [Typography] Heavy brush-block display type with slightly rough edges in cobalt blue, paired with a flowing italic serif and a thin vertical Chinese-free sans tagline. [Subject] A plump green tree character with round cartoon eyes, rosy halftone cheeks and leafy arms, holding a wrapped gift, surrounded by polka-dot, checked and striped present boxes on a snowy mound. [Lighting & mood] Flat even light, printed-paper feel, visible dot screens and light grain, playful and nostalgic. [Details] Halftone dot shading across the tree body, hand-drawn starburst sparks in opposite corners, torn-paper edges on the gifts. Text: "MERRY CHRISTMAS".
