Use case: style-transfer. Asset type: Heroes of Might and Magic III Necropolis creature showcase background, an empty environment behind a separately rendered creature. Image 1 is the edit target: original CRBKGNEC background enlarged for reference. Repaint it in much higher definition while faithfully preserving its composition and camera: ruined grey stone tower in the upper left, dark distant mountains near the upper middle, pointed barren rocks on the right, brooding cloudy charcoal sky, cracked grey-brown barren ground occupying the lower half. Preserve the existing muted dark palette and illumination, horizon height, ground perspective, and the unobstructed central standing area. Add crisp believable masonry, rock strata, soil and subtle cloud detail, with restrained painterly realism consistent with a polished classic fantasy strategy game. Keep the background subdued so a pale skeleton or zombie sprite remains readable. Full-bleed portrait image, aspect ratio 10:13, high resolution. No creatures, people, weapons, gravestones, UI border, lettering, labels, logos, glow, or watermark. Do not add a focal object in the middle. Output the background alone.
