Elegant Crystal Christmas Greeting Poster

Professional Christmas greeting poster, vertical, crystal product render with photographic realism. [Colors] Midnight indigo and steel blue (#142C4E, #4A6E92), mirror-silver facets, and liquid champagne gold (#D9B26A) for the type. [Layout] A large gold script headline floating across the upper third, a crystal tree standing dead centre on a reflective slab, a quiet centred date and wish line low in the frame, and a small contact strip at the very bottom. [Typography] Flowing formal script with thick-thin strokes and slight bevel, in polished gold, with small refined serif caps for date and greeting. [Subject] A Christmas tree carved from faceted crystal, stacked in four tiers of prismatic glass with sharp geometric ridges, topped by a starburst crystal star, standing on a frosted glass plinth with a soft mirrored reflection. [Lighting & mood] Cold blue backlight refracting through the glass, warm gold accents, high clarity, premium and serene. [Details] Caustic light streaks inside the facets, drifting snowflakes, misty blue gradient backdrop, subtle lens flare on the star. Text: "MERRY CHRISTMAS", "DEC 25".
