"Create a 4K ultra-high-resolution masterpiece depicting a solemn cardinal in traditional black-and-red ceremonial attire. The cardinal should be shown in a dynamic action pose with his right hand over his chest and left hand holding a white document. The composition must follow the golden ratio with isometric perspective, featuring a beautifully detailed background of blurred greenery and distant figures. Render the image using Unreal Engine 5 with Octane Render technology to achieve lifelike textures in the cardinal's robe and zucchetto. Apply Raphael's classical aesthetics combined with Houdini's procedural detail work, while incorporating Grammer Effect lighting for dramatic impact. The face should exhibit meticulous detail with expressive eyes conveying both authority and contemplation. Use a harmonious color palette with vibrant red accents against deep black and natural green tones. Ensure the final piece meets ArtstationHQ trending standards with balanced editing and sharp brush strokes."
