```
This prompt adds more scene details like neon lighting, glowing circuits, mist, and bioluminescent elements to enhance the cyberpunk and mystic atmosphere. The aspect ratio is set to 16:9 for a cinematic look, with a high stylize value of 750 to emphasize the unreal quality. A moderate chaos value of 20 adds some unpredictability, and the weight of 2 gives extra emphasis to the main concepts.
