Fantasy educational poster illustration in 4:5 aspect ratio (1080x1350) based closely on the reference image: A powerful male warrior in ornate dark crimson-red plate armor with glowing red ruby crystals on shoulders and chest. Swirling red glowing energy and red blood cells (erythrocytes) spiral around him. In the center floats a luminous red glowing magical sphere with the chemical symbol "Fe". At the bottom, neat glowing text in Russian: «Железо входит в состав гемоглобина крови». Epic fantasy lighting, cave/laboratory background, highly detailed digital painting.
