Alien skull megacities glowing within a dense jungle

A surreal alien landscape featuring colossal skulls with elongated craniums partially buried in a lush, vibrant jungle. Inside the hollow cranial cavities, intricate futuristic megacities glow with neon lights and sleek architecture, bustling with tiny humanoid beings. Suspended super tramways weave between the skull cities, while sleek, aerodynamic ships glide gracefully through the humid air. Massive metallic conduits snake outward from the skulls across moss-covered ground, connecting to towering, gleaming cold fusion reactors emitting a soft bluish-white energy glow. The scene is bathed in ethereal green light filtering through dense jungle foliage, with mist rising from the undergrowth, creating an atmosphere of otherworldly wonder and advanced technology harmonizing with alien nature.
