This was created during the “Light and Darkness: Fall into Darkness/Evil” event.
The flames are so long they look like they're coming out of its nose...
By the way, you can see the successful version at the link below.

Model: Nova Anime XL IL v6.0
1girl, upper body, three-quarter angle, slightly angled view,
beautiful and dignified young woman, serene and noble expression,
elegant facial features, clear luminous skin, soft pale coloring,
delicate shading, subtle gradients, translucent highlights,
watercolor-like softness, long silky hair with gentle volume,
detailed eyes with soft reflections, saint-like presence,
a delicate ceremonial silver circlet on her head,
fine sacred motif hair ornaments catching faint candlelight,
a thin translucent ceremonial veil flowing behind her,
subtle silver embroidery woven into the veil,
the veil’s white patterns partially corrupted by dark shapes,
black tendrils creeping through the embroidered motifs,
inky darkness spreading across the veil like a growing stain,
visible dark patterns overtaking the lower part of the veil,
shadowy corruption clearly contrasting against the pale fabric,
from behind her hair and veil, thick dark mist rising upward,
dense shadowy tendrils flowing heavily from the back of her head,
darkness pouring from the veil’s edges like slow smoke,
deep black haze spreading outward and merging with the cathedral’s shadows,
the darkness is heavy, visible, ominous yet silent,
luxurious white and silver ceremonial robes,
heavy ornate fabric, rich embroidery, sacred motifs, layered textures,
standing inside a vast ancient cathedral shrouded in deep darkness,
towering stone pillars fading into shadow,
massive vaulted ceiling disappearing into darkness above,
colossal stained glass windows present but unlit, faint silhouettes only,
rows of tall brass candelabras with flickering flames,
warm candlelight as the sole light source, soft firelight reflections,
Rembrandt lighting created by candlelight,
one side of her face softly illuminated,
a small triangle of warm light under the eye on the shadowed side,
overall very low-key lighting, muted background colors,
majestic, solemn, overwhelmingly sacred atmosphere
