[A dark fantasy concept art of an anthropomorphic raven sorcerer with a glowing green eye. The character wears a tattered, hooded black robe stitched with leather straps, buckles, and hanging pouches. In one hand, he holds a gnarled wooden wizard staff emitting glowing pale green smoke and wisps of magic; in his other clawed hand, he summons swirling dark and green magic energy. Highly detailed monochrome grayscale digital painting, dark gothic atmosphere, ash and smoke particles floating in the air, cinematic lighting, ultra-detailed, 8k resolution.]
