Design a breathtaking 3D architectural villa nestled in a surreal desert oasis. Imagine an intricate glass and crystal structure emerging from the sandy dunes, catching and refracting the sunlight. The villa’s form should echo the organic lines of nature, with flowing walls that blend seamlessly with the landscape. Surround the oasis with diverse vegetation, from towering palm trees to delicate succulents. Illuminate the scene with artificial lighting that accentuates the play of light and shadow both inside and outside the villa, creating an ethereal atmosphere.
