Use reference image 1 as the holy armored female knight, and reference image 2 as the massive toxic forest beast. 
A 15-second cinematic game CG battle sequence in a dark forest filled with green-black miasma, dead trees, wet ground, drifting poisonous fog, faint moonlight cutting through the canopy.

Visual style: stylized high-end game cinematic, bold graphic shape design, large color-block sculpting, reduced fine detail, low texture noise, hard-edged shadow transitions, faces and armor defined by large geometric planes of light and shadow, painterly but not overly realistic, clean silhouettes, dramatic readability, concept-art character design translated into natural cinematic motion.

Scene: the holy knight in white, gold and dark armor stands in the mist with a glowing sword and shield. Across from her, the huge purple-black swamp predator crawls out of toxic fog, spines raised, glowing violet wounds and venom dripping from its jaws.

0-3s: low tracking shot through poisonous fog and broken roots, revealing both characters facing each other. The knight lowers her stance, sword tip scraping the wet ground, golden light gathering around her armor. The beast circles heavily, claws sinking into mud, purple poison vapor leaking from its back.
3-6s: the beast suddenly charges, shaking the forest floor, releasing a wave of violet toxic miasma from its mouth. Camera rushes backward with the impact, branches whipping past the lens.
6-9s: the knight raises her shield and releases a hard-edged golden barrier, the poison wave crashes against it, gold and purple energy splintering into large graphic shards. Close-up on her focused eyes, face lit by bold angular planes.
9-12s: she dashes forward through the collapsing fog, golden sword forming a long radiant spear trail. The beast whips its tail and slams the ground, toxic spikes erupting from the mud around her.
12-15s: final clash in slow motion: the knight leaps and strikes downward with a blinding holy blade while the beast lunges upward with violet venom jaws open. Gold and purple energy explode in the center, fog rolls outward, silhouettes freeze for a dramatic final frame.

Camera: dynamic third-person action camera, low angles, fast push-ins, whip pans, brief slow motion at impact, strong foreground fog layers, readable silhouettes, cinematic depth, no shaky chaos.
Mood: tense, dangerous, epic, high-stakes, trailer-like, immediately gripping.
