"Hyper- realistic depiction of a massive, crystalline tree growing out of a futuristic, underwater cityscape. The tree's branches are adorned with glowing, bioluminescent orbs, while its trunk is covered in intricate, swirling patterns that reflect the colors of the surrounding ocean. Schools of rainbow- colored fish dart through the city's streets, while a giant, mechanical octopus rises from the depths, its tentacles wrapping around the tree's trunk. In the distance, a massive, glowing portal pulses with energy, illuminating the dark ocean waters. Style: extremely detailed, hyper- realistic, and cinematic, with a focus on capturing the vibrant colors and dynamic energy of the scene. "
