Prompt

An image of a {argument name="type" default="[TYPE]"} landscape, featuring a cave entrance that is shaped exactly like the outline of a {argument name="shape" default="[SHAPE]"}. The cave should blend naturally into the rugged terrain of the mountain, with the entrance forming a clear and unmistakable {argument name="shape repeat 1" default="[SHAPE]"} shape. This {argument name="shape repeat 2" default="[SHAPE]"} shape should be simple and defined, without intricate details, emphasizing just the overall {argument name="shape repeat 3" default="[SHAPE]"} outline. The surrounding environment should include {argument name="details" default="[DETAILS]"}, but these elements should not distract from the cave's   {argument name="shape repeat 4" default="[SHAPE]"}-shaped entrance. The lighting in the scene should enhance the visibility and distinctiveness of the {argument name="shape repeat 5" default="[SHAPE]"}-shaped cave entrance.
