# Heimdall r1b

## Hypothesis

Adding the canon bust as a reference image holds canon details the prompt alone drifts on, without pulling every cell into the bust's pose.

## Variable changed

Against the same character's r1a: the canon bust cutout on its chroma green is passed as `images` and cited as image 1 by one clause prepended to the prompt. Nothing else differs.

## Prompt

Image 1 is the character's canon bust. The character must look exactly like the character in image 1 (same design, colours, proportions and line style) in every cell.

Character expression sheet for a game cast lineup: a sheet of twelve cells, each cell a bust, head and shoulders cropped at mid-chest by the bottom edge of the cell, the character in three-quarter view turned toward the right side of the cell, the head centred horizontally in the cell with its top a small margin below the top edge of the cell, the same crop and scale in every cell. Super-deformed chibi proportions: the character is two heads tall in total, so the head is very large compared with the small shoulders and narrow torso. Clean 2D anime illustration drawn to be traced into vector art: one bold dark outline of even weight around the whole silhouette, thinner inner lines, flat cel shading with exactly one base tone and one shadow tone per material, light from the upper left. No gradients, no texture, no painterly blending, no glow halos, no pixel art, no 3D rendering. A limited palette of five or six flat colours taken from the character's key colours. Large expressive anime eyes with two white highlights. The background is one perfectly flat, uniform, solid bright chroma-key green from edge to edge: no gradient, no vignette, no floor, no cast shadow, no particles, no props or scenery behind the figure.

The sheet is a grid of four columns by three rows, twelve cells of the same character in reading order, left to right and top to bottom, separated by generous empty padding of the same flat green, with no frames, no borders, no divider lines, no labels and no text. Every cell shows the same character with the same design, colours and proportions; the cell description sets that cell's expression and pose, and the character description below gives the design.

Heimdall, a stern young gatekeeper: dark brown skin, a mop of messy dark brown curly hair with golden highlights, glowing golden amber eyes, a serious frown, one small gold earring. He wears a high-collared black coat with royal blue lapels and a royal blue cape trimmed in gold filigree, small blue gems on the shoulder armour, and a gold key-shaped clasp at the throat. He holds an ornate golden key raised beside his shoulder. Key colours: gold and cobalt blue.

Cell 1 (neutral): a calm neutral expression, mouth closed, looking ahead. Cell 2 (happy): a broad happy smile with bright eyes. Cell 3 (amused): an amused smirk with one eyebrow raised, a stifled laugh. Cell 4 (thinking): a thoughtful expression, eyes looking up and aside, one hand raised to the chin. Cell 5 (concerned): a concerned expression, brows drawn together and tilted up, a small worried frown. Cell 6 (annoyed): an annoyed expression, flat half-lidded eyes, a pursed frown. Cell 7 (surprised): a surprised expression, wide eyes, mouth open in an O. Cell 8 (determined): a determined expression, narrowed eyes, a firm set mouth, a small nod. Cell 9 (badge): holding up a gold badge of authority toward the viewer. Cell 10 (barrier): one palm raised forward, projecting a blue barrier. Cell 11 (protect): stepping forward with his cape swept out in front, shielding someone behind him. Cell 12 (revoke): pointing the golden key downward with a sharp cross-out gesture of the other hand, revoking access.
