Art style: Comic Book.
Guardian stands before a massive window, looking out at the sprawling city he saved. His reflection in the glass shows his younger, caped self, a faint, heroic echo. The city lights are a stark contrast to his somber mood. Marvel cinematic concept art style.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Comic Book" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Comic Book". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Comic Book" idiom, not in any other medium.
