Affiche publicitaire pour limonade aux myrtilles fraîche

A commercial beverage advertisement poster featuring a large transparent plastic cup filled with chilled [blueberry lemonade] as the centered hero product. The drink shows a rich purple-blue gradient, sparkling ice cubes, thin submerged lemon slices, and fresh whole [blueberries] floating inside, with a black straw protruding from the top. Realistic condensation beads coat the exterior of the cup. Floating dynamically around the drink are fresh [blueberries], lemon halves, lemon slices, green mint leaves, crystal-clear ice cubes, and suspended water droplets. The background is a modern split layout with deep navy blue on the left and soft lavender-purple on the right, decorated with subtle gradients and rounded geometric shapes. On the left side, bold vertical white typography in a clean modern sans-serif reads "BLUEBERRY". In the upper right corner, minimalist white text reads: "THE BEST IS HERE AT [HEIS DRINKS]" Dramatic studio lighting with glossy reflections, soft contact shadows, sharp focus on fruit textures, and a polished luxury advertising aesthetic.
