Behind A Door - Halloween

Anime-style girl in a tattered school uniform, pale skin, hollow eyes, standing before an ancient wooden door cracked open, eerie blue glow emanating from within, ghostly wolf silhouette looming behind the door, fur rippling like smoke, fangs bared, fierce spectral aura, halloween moonlight casting long shadows, chilling horror aesthetic, ominous horror concept art, extreme tension, wide-angle shot, dark corridor, supernatural atmosphere, highly detailed, eerie silence, cold tones with crimson accents.
