Generate a high-resolution portrait in the style of a High Renaissance oil painting, reminiscent of masters like Titian or Raphael. The central subject should be a dignified figure of European nobility, depicted in an elaborate 16th-century period costume, featuring rich velvets, brocades, and intricate lace, adorned with subtle jewels. The figure should be captured in a three-quarter length pose, exhibiting a serene yet commanding expression. The background should feature a classical architectural setting, such as an opulent hall with ornate columns or a detailed Italianate garden, subtly illuminated by soft, natural light, enhancing the overall depth and realism typical of the era. Focus on meticulous detail in textures, fabrics, and facial features, utilizing chiaroscuro to add dramatic contrast and depth.
