A large incense burner is seen swinging from the ceiling, trailing smoke that curls around the space. The central focus is on a procession of robed figures carrying different ornate objects and items. The floor shows a reflection of light, suggesting a polished surface, and the overall scene is filled with a sense of reverent solemnity and grandeur. The light and shadow work brings depth to the image.
