Black Friday Serum Sale Poster

Professional Black Friday e-commerce sale poster, vertical 9:21, celebratory red-gold skincare spotlight style. [Colors] Background is a rich crimson-red gradient (#b01020 range) with golden city skyline silhouettes, floating gold tickets and fireworks bursting at the top corners; giant glowing gold-outlined numerals "70" dominate the centre; the serum bottle is clear red glass with a gold collar; date type is white on red; bottom badges are white line icons. No frame border. [Layout] A small logo chip and "YOUR LOGO" sit top-centre; the main headline runs beneath with a dash-framed sub-line; the huge glowing "70" fills the middle of the frame; the serum bottle stands front and centre on a round red-lit podium overlapping the numerals; a gold-bordered date slab sits below the podium; a row of three small icon badges lines the bottom edge. [Subject] No people. A faceted clear glass serum dropper bottle filled with ruby-red liquid, gold collar and white rubber pipette cap, standing on a glossy circular red podium with a bright rim light; golden foil tickets flutter down and gold fireworks crackle above a stylised city skyline behind. [Headline] Upper block in heavy cream-gold display caps: "BLACK FRIDAY PEAK EVENT"; beneath, a dash-framed line "Best-Selling Serums · Slashed To The Floor". Below the podium, a small red tag reads "Event Dates" above large white type "Nov 24 - Dec 1". [Badges] Bottom edge, three small white icon rows: "Authenticity Guaranteed" (diamond icon), "Fast, Reliable Fulfillment" (truck icon) and "Best-Price Promise" (shield icon), each with a tiny sub-line. [Mood] Grand, glittering and triumphant; a red-and-gold night skyline crowning one hero serum for the year's biggest sale.
