Seamlessly extend the image beyond its edges using outpainting. Do not create any frame, border, or duplicate box of the original image. The original image must remain fully intact and blended naturally into the expanded scene. Only generate new content in the empty outer areas, keeping the center subject completely unchanged (no edits to face, body, or armor). Extend the rocky environment realistically with matching textures, perspective, and lighting. Add subtle floating stone particles and light dust only in the extended regions. Ensure perfect blending between original and generated areas with no visible seams. Add a very mild cinematic depth effect (slight atmospheric haze and soft background blur) to give a gentle 3D feel, but keep everything minimal and realistic. Avoid over-stylization, avoid high contrast glow, avoid duplication artifacts.
