Watercolor Alien in an Oasis

A richly detailed watercolor-style illustration of an alien standing in an oasis. The alien has smooth iridescent skin, large almond-shaped eyes, slender limbs, and subtle tentacle-like appendages curling from its shoulders. It stands at the edge of a tranquil pool, with palm trees and cattails around it. The water reflects the alien and a twilight sky; the sun is setting, casting gold, pink, and turquoise washes. The scene should be painterly with soft edges, color bleeds, and grainy texture typical of watercolor on textured paper. Use cool greens and blues for the oasis and warm amber for the sunlit sand. Add gentle ripples, droplets on leaves, and a sense of quiet wonder, with a surreal yet serene sci-fi fantasy vibe; composition centers the alien while the oasis frames the scene.
