Star-Shaped Cave Wonder

A mountain landscape painting with a cave entrance whose shape perfectly matches the outline of the stars. The cave should naturally blend into the rugged mountainous terrain, with the entrance forming a clear and unmistakable star shape. This star shape should be simple and clear, without complicated details, only emphasizing the overall star outline. The surrounding environment should include pine trees and rocks, but these elements should not distract from the star-shaped entrance of the cave. The lighting in the scene should enhance the visibility and uniqueness of the star-shaped cave entrance.
