Create a digital portrait of Superman adorned in sleek, cybernetic armor complete with a sophisticated helmet. This sci-fi rendering should showcase glowing, intricate designs with a full-body view, embodying elegance and high detail. The artwork should reflect the styles found on ArtStation, inspired by the conceptual artistry of Artgerm, Greg Rutkowski, and Alphonse Mucha. Ensure the image is smooth and sharply focused, capturing the essence of a detailed illustration. Pay attention to anatomical accuracy and harmonious proportions, avoiding distortions like extra limbs or deformed features. Keep the presentation clean and professional, free from any visual imperfections such as blurriness, low resolution, or distracting elements like watermarks or text errors.
