Remix in builder

100% of our 527 tested Stable Diffusion prompts ship a negative prompt — from the tested Promptkoi prompt library.

How to use this prompt

"Horror" and "creepy" in the negative prompt are essential — giant forest creatures drift unsettling fast without them, and "gentle" alone won't hold the line. The child is the scale anchor and the emotional read; remove her and you get a creature sheet instead of a scene. Two light sources (god rays + mushroom glow) give SDXL the depth cue that makes the composition feel layered.

Variations to try

Winter spirit — "made of ice and bare branches, snowfall, cool blue palette with one warm lantern"
Tiny spirit — invert the scale with "palm-sized moss spirit sitting on a child's outstretched hand"
