+# Three-quarter skull
+
+A 48 × 48 skull facing right, drawn in native Pixelsrc regions with a warm bone
+ramp, angular recessed sockets, a notched nose, cheekbone and separate mandible.
+The source reference remains in
+[`../avatar-prototype/reference-skull.jpg`](../avatar-prototype/reference-skull.jpg).
+
+![Reference at left, Pixelsrc at right](comparison.png)
+
+![Talking skull](skull_talking.gif)
+
+## Render
+
+From the repository root, build `pxl` with `cargo build --bin pxl`, then use that
+binary (or an installed `pxl`) for these commands:
+
+```sh
+pxl validate --strict examples/skull/skull.pxl
+pxl validate --strict examples/skull/skull_talking.pxl
+pxl render examples/skull/skull.pxl --composition skull --strict -o examples/skull/skull.png
+pxl render examples/skull/skull.pxl --composition skull --strict --scale 4 -o examples/skull/skull_4x.png
+pxl render examples/skull/skull.pxl --composition skull --strict --scale 8 -o examples/skull/skull_8x.png
+pxl render examples/skull/skull_talking.pxl --animation skull_talking --gif --strict --scale 4 -o examples/skull/skull_talking.gif
+pxl render examples/skull/skull_talking.pxl --animation skull_talking --spritesheet --strict --scale 4 -o examples/skull/skull_poses.png
+```
+
+Every sprite PNG and the GIF are direct `pxl` output; no painted raster assets
+or post-render retouching. The background is transparent. The GIF loops through
+closed → small → wide → small at 120 ms per frame. The cranium stays fixed;
+the mandible drops by one or three logical pixels with a dark cavity behind it.
+
+Both `.pxl` files are standalone examples. The still's palette and components
+are repeated verbatim at the beginning of `skull_talking.pxl`; keep that prefix
+in sync when changing the design. Validate the two files separately, since
+validating them together treats their intentionally shared names as duplicates.
+
+The talking file uses explicit jaw-pose regions. In the current renderer,
+composition-layer `shift` and source-sprite `shift` inside compositions silently
+render the unshifted pose, even though direct rendering of the shifted sprite
+works. This compiler limitation is tracked separately with an 8 × 8 reproducer;
+the example does not rely on those transforms.
+
+## Comparison and visual checks
+
+`comparison.png` is a presentation image only: the existing reference enlarged
+with nearest-neighbor sampling beside the unmodified 8× Pixelsrc render on white.
+Regenerate it with ImageMagick:
+
+```sh
+magick \
+  \( examples/avatar-prototype/reference-skull.jpg -filter point -resize 384x384 \
+     -background white -gravity south -splice 0x24 -font DejaVu-Sans \
+     -pointsize 14 -annotate 0 'Reference' \) \
+  \( examples/skull/skull_8x.png -background white -alpha remove -alpha off \
+     -gravity south -splice 0x24 -font DejaVu-Sans -pointsize 14 \
+     -annotate 0 'Pixelsrc - 48 x 48' \) \
+  +append examples/skull/comparison.png
+```
+
+Iterations inspected at 1× and 8×:
+
+- Initial geometry: rounded back-left dome and asymmetric sockets established
+  the turn; tooth rows were too short and the chin too empty.
+- Dental revision: taller individual teeth and umber separators improved the
+  bite; retained the cream forehead and beige side planes.
+- Motion revision: explicit jaw poses replaced ineffective transforms. A dark
+  mouth cavity keeps the opening readable on white as well as dark backgrounds.
+
+Final checks: recognizable silhouette, readable at native size, consistent
+upper-right lighting, transparent margins, three distinct jaw poses, identical
+upper cranium across frames, and no strict-validation warnings. The older
+avatar-prototype skull sources and renders have been retired in favor of these
+examples; the reference image is unchanged.
