Portal of the Cosmic Oasis

Prompt:  A mystical ancient portal in the shape of a triangle with an eye at the center overlooking a serene desert oasis. Majestic palm trees adorn the sandy banks, and a crystalline waterfall flows through the gate, cascading into a tranquil pond below. In the background, towering pyramids stand tall among the rocky desert cliffs. A mesmerizing extraterrestrial sky with a large purple moon, distant planets, and swirling galaxies adds a surreal atmosphere to the scene.
