To enhance the image and make it appear more realistic and beautiful, you can use a text-to-image model like Midjourney or Stable Diffusion with the following prompt: "Create a hyper-realistic and stunning portrait of a Na'vi character from the movie Avatar, with detailed and vibrant blue skin, intricate patterns, and glowing yellow eyes. Emphasize realistic textures, lighting, and depth to bring the character to life, highlighting their otherworldly beauty and intricate jewelry." This prompt can be fine-tuned depending on the specific text-to-image model you are using.
