Use case: stylized-concept. Asset: ONE transparent top-down JRPG environment prop: a modest entrance into the SQUARE CITADEL TOWER of Mock's Hold.
Reference gives pale battered limestone material and pixel palette only. Create a standalone orthogonal top-down/three-quarter RPG tower-front/doorway segment that can be placed behind characters on a tile map. Square wall masses and a simple dark entrance, worn limestone blocks, a short flat stone threshold. No entire castle, city, courtyard or perspective panorama.
Logical prop96x128 pixels, rectangular tower facade with shoulders and hint of its top plane. Main dark doorway about32 pixels wide at bottom centre, wide enough for a single character, with thick rough masonry jambs and a plain lintel or restrained shallow stone arch. Interior black and unlit, no glowing magic. No ornate Gothic detail. Do not invent banners, flags, crests, statues, runes, torches or emblems.
Match muted warm pale limestone and cool grey-mauve shadows, upper-left diffuse smoke-muted daylight. Strong chunky pixel clusters, restrained cracks and wear, clean stepped contours, few shades per material. It must read at96x128, not be a miniature high-resolution painting.
One standalone prop on true transparency, complete outline, small padding; no ground outside threshold, cast shadow, glow, grid, labels, text, palette swatches or characters.
