天使的で陰鬱な姿が調和するダークな天界デザイン

design featuring a balanced mix of angelic and eerie elements. Two majestic angels with flowing robes and serene expressions, embodying divine grace, one has black hair and wings on the right and a white winged angel on the left. Two representations of death, including a menacing skull with intricate details on the right and a haunting female with blindfolded eyes on the left. The design should evoke an eerie yet balanced atmosphere--half grim imagery, half celestial beings. Smooth transitions between elements, high contrast, deep shadows, and sharp highlights.
