Highland Yak Milk Fresh Dairy Poster

[Format] Professional e-commerce product main image, square 1:1, fresh pasture dairy advertising style with an alpine blue-and-green palette. [Colors] A highland meadow scene: blue sky with soft clouds, snow-capped mountains and rolling green grass; white milk cartons and splashing milk bring brightness; deep blue headline type with a sky-blue banner; blue coupon blocks on the right. No frame border. [Layout] A white tilted headline card spans the top with a small blue trust strip above it. Two milk cartons stand centre on the grass, one larger and one smaller, with a milk splash curling across the base. A blue coupon column sits at the right edge with three stacked chips. The bottom band is sky blue holding a price card on the left and a membership deal in the centre. [Subject] White gable-top milk cartons with a blue-and-green circular label showing a glass of milk, a yak silhouette and mountain artwork, "Yak Milk" in bold characters, net-content line beneath; a dynamic arc of splashing white milk sweeps across the foreground; dewy alpine grass below, snow peaks behind. [Headline] Top blue strip: "Direct from source ranch, no additives for peace of mind". Main headline on the tilted white card: "Highland Yak Milk, Cold-Chain Fresh" in deep blue. Right coupons: blue chips reading "$10 new-customer coupon" and "$20 follow coupon" over "The more you order, the more you save". Bottom-left: "Member price $5.9 per bottle" with "$5.9" huge. Bottom centre: "Join and apply coupons for an extra $5 off" in dark blue; a small corner note reads "Rich milky aroma, gentle on the stomach". [Badges] Small blue logo tag top-right; blue coupon chips at the right edge. [Mood] Pure, pastoral and refreshing; alpine air with creamy white and glacial blue, farm-fresh trust at thumbnail size.
