Create a premium, ultra-realistic beverage advertisement poster featuring a large transparent plastic cup filled with vibrant blueberry lemonade. The drink has a rich purple-blue gradient, sparkling ice cubes, fresh whole blueberries floating inside and around the cup, and thin lemon slices submerged throughout. The cup is covered with realistic condensation droplets, creating a refreshing, chilled appearance. A black drinking straw extends from the top.
Surround the drink with floating fresh blueberries, lemon halves, lemon slices, mint leaves, water droplets, and crystal-clear ice cubes for a dynamic composition. Use dramatic studio lighting with glossy reflections and soft shadows to create a luxury commercial look. Background consists of a modern split design with deep navy blue on the left and soft lavender-purple on the right, including subtle gradients and rounded geometric shapes. Place the beverage in the center as the hero product. Add bold vertical white typography on the left reading "BLUEBERRY" in a large modern sans-serif font. On the upper right, include a clean promotional text layout:
