Prompt: Craft an oil painting concept featuring an elderly Strix bard in the Pathfinder RPG universe. Illustrate the character's hauntingly beautiful music as they play a distinctive wearable drum kit. Emphasize the monstrous black-feathered wings enveloping their leanly muscled, onyx-skinned humanoid form. Clearly depict the face with human-like features, avoiding any bird-like characteristics. Highlight the details of the wearable drum kit, considering the Strix's advanced age and its impact on both their appearance and musical style. Convey the character's background, personality traits, and the mystical nature of their wings through the visual narrative of the oil painting.
