Dune Ridge · Slip-Face Deposition

EXPRESSION
Neutral. Resting baseline: release all facial tension.
BROWS: Rest at their natural height without pulling together.
EYES: Rest at natural openness; no squint or widened stare.
CHEEKS: Remain relaxed without lift or nose wrinkling.
MOUTH: Keep lips gently touching and corners level.
JAW: Keep teeth apart slightly behind closed lips; jaw relaxed.
GAZE: Look straight at the viewer with aligned pupils.
EXPRESSION SCOPE: Apply only these facial movements; intensity changes movement amplitude, not identity or rendering style. Keep the head angle, body pose, framing and illumination supplied by the other modules. Use viewer-left/right consistently. Do not add tears, sweat, blush colors, symbols or props unless separately requested.

FACIAL MUSCLE COORDINATION
Resting baseline: release expressive brow, cheek and lip tension. Maintain ordinary eyelid support and comfortable lip contact; leave the jaw unclenched. No unilateral pull, squeezed lids or residual smile.

FACE IDENTITY
IDENTITY: One original adult character, approximately 28 years old, with an androgynous appearance; the same individual in every expression.
PROPORTIONS: Oval face with face height about 1.35 times cheekbone width; eye line near mid-height, with approximately one eye-width between inner eye corners.
EYES: Medium almond-shaped eyes, dark brown irises of equal size, defined upper eyelid folds and gently curved lower lids; preserve inner and outer corner locations.
BROWS: Medium-width straight eyebrows with a soft arch in the outer third; dark brown, with a softly tapered outer tip and a rounded inner end.
NOSE: Straight narrow bridge, softly rounded tip and small symmetrical nostrils; nose base width approximately equals the inner eye-corner distance.
MOUTH: Moderate-width mouth, defined but shallow cupid bow, lower lip slightly fuller than upper lip; preserve resting lip volume and philtrum length.
JAW: Softly tapered jaw, rounded chin and moderate cheekbone projection; ears of equal size at consistent positions beside the head.
SKIN: Even medium warm-brown complexion; keep the same underlying tone and age impression, without expression-dependent changes in skin texture.
HAIR: Short dark brown hair, straight side part at viewer-left, forehead visible, no bangs across the eyes and no facial hair.
MARKS: One small round mole below the viewer-left outer eye corner, about one iris diameter beneath it; no additional freckles, scars or accessories.
These describe the resting identity, not the final expression. Preserve bone structure, landmark spacing, iris size, hairline, age impression and distinctive marks. Only the requested soft-tissue motion may change.

RENDERING STYLE
1. Use long smooth contours on windward slopes and a sharper broken edge at the crest; draw falling material as short directional streaks.
2. Keep the windward plane broad and evenly lit; give the steep lee plane a single deeper value and the fresh fall a narrow light accent.
3. Concentrate fine grain and tiny ridges where material accumulates; leave undisturbed planes almost smooth.
4. Repeat the same slope relationship at smaller scales into the distance, while keeping one dominant crest unmistakable.
STYLE AVOID: Avoid random ripples across every surface, identical slope angles, dramatic color effects that obscure terrain, lettering, logos, and watermarks.

PORTRAIT FRAME
One head-and-shoulders portrait, square frame, face centered, eye-level straight-on view with zero head roll. Hair and chin fully visible; head occupies about 60% of frame height. Plain light neutral background. Keep the same crop and softly even illumination across the set; use only the shading methods supported by the selected style.

MODULE PRIORITY
Identity landmarks first, facial movements second, fixed portrait framing third; transfer contour, palette relationships, shading and texture from the style. A style-only reference must not supply its identity, facial expression, hair, costume, head pose or scene. Translate movement into the style without adding realistic wrinkles or glossy volume to a flat style. Resting mouth/eyelid descriptions yield only to the requested movement, not to a different identity.

QUALITY CHECK
Check the same face outline, eye spacing, nose shape, resting lip proportions, hairline and identifying marks across the set. Check each requested brow, lid, cheek, lip, jaw and gaze movement. Keep anatomy coherent and preserve the chosen rendering technique. No added labels, lettering or watermarks.
