Dark fantasy style, with a Gothic-themed blue background as the main focus, an elder is playing the erhu, wearing a white t-shirt, with a close-up of his face from an upward angle. He is passionately performing with long hair flicking as his eyes are closed, showing a deeply immersed expression that exudes his temperament and charm. Behind him is a misty backdrop, with the stage lights flickering, giving off a sense of mysticism. The atmosphere is lively. The top lighting of the photography creates a hazy sense of depth, with a contemporary oil painting effect, free and bold brushstrokes, and strong artistic expression. Ultimate CG, masterful composition.
