Old Santa Claus Portrait, Classical Oil Painting Style: A Stylized Take

Imagine: old Santa Claus portrait in classical oil painting style, inspired by old master paintings. A serious, dignified Santa, not smiling, powerful presence, deep shadows, warm highlights on skin and beard. Heavy oil texture, thick expressive brush strokes, dark background featuring subtle gold and brown tones, strong chiaroscuro lighting, emotional realism. Painterly realism, fine art, gallery-level oil painting, dramatic and timeless. Refine: name the rendering engine you want (Octane, Cycles, Unreal) for sharper output.
