Multi-stage prime with micro-fill to sharpen panel lines before color. Modulated gunmetal/iron black base for armored depth across torso and limb plates. Edge pre-shade around hatches and vents to push form under neutral light. Hand-masked sector blue service panels with controlled sponge-chipping back to steel. Brush and sponge chipping on knees, elbows, ladder rungs and hatch rims for contact wear.
Pin-washes (Payne's Grey / dark umber) to sink into bolts, grills, and missile-bay seams. Oil streaking pulled vertically from fasteners and access panels to simulate rain-dragged grime. Dry-brush passes in titanium silver to pop rivets, knuckles, and ladder edges. Graphite rub on leading corners, gauntlets, and boot rims for polished metal sheen. Heat staining on the twin mortar barrels (blue-violet/brown transitions) with carbon soot at the mouths.
Soot and blast scoring around the rotary vent and shoulder launcher, airbrushed charcoal for plasma residue. Oxide rust mapping on ankle clamps and rear rams using burnt sienna/black oil blends. Fuel and hydraulic spills glazed around belly tanks and couplings with satin enamel. Dust pigments (ochre/ash) packed into tread crevices and piston guards, fixed then partly buffed off for tracked-in grit.
Micro-scratches along cockpit brow and comms housings to suggest tool use and helmet rub. Unified ultra-matte seal with selective gloss on lenses, gauges and hydraulics for a cinematic finish. Heavy shoulder missile pod and twin plasma mortars with weathered interiors. Panoramic visor canopy with tactical HUD markings and in-universe stenciling (OS-221).
Hand-crafted, one-of-a-kind build - no duplicates. Keep the gates shut and the Sentinel awake. If they come for us, let them find death! - Extract, Outpost Aurek Security Log, Kuat Systems Field Manual Thanks for looking, Josh.
