a highly detailed and realistic CGI rendering of Barbarella, the iconic character from the 1968 science fiction film, using Unreal Engine. The image should capture Barbarella's signature look, including her futuristic and revealing space suit, her long flowing hair, and her confident, adventurous demeanor. The setting should be a futuristic, otherworldly landscape with vibrant colors and intricate details, reminiscent of the film's psychedelic aesthetic. Ensure the lighting is dramatic, with a mix of natural and artificial light sources to enhance the character's features and the environment's depth. The final image should be a high-resolution photographic quality render, suitable for use in modern media and promotional materials.
