Fantasy educational poster illustration in 4:5 aspect ratio (1080x1350) based closely on the reference image: A young handsome alchemist/mage with reddish-brown hair in ornate copper and bronze armor/robes, casting magic beside a luminous mystical octopus with glowing cyan-blue blood/energy. In the center floats a glowing warm bronze-orange magical sphere with the chemical symbol "Cu". Background has steampunk copper pipes, alchemy tanks, and glowing magical symbols. At the bottom, clear legible Russian text on a parchment/panel banner: «Медь в составе белка гемоцианина в крови беспозвоночных». Rich fantasy art, dramatic lighting, detailed composition.
