Ancient treant forest city forming a vast organic metropolis

A massive ancient treant forest city, enormous living trees grown together into a sprawling organic metropolis, bark surfaces covered in spiraling growth patterns like giant fingerprints, tree trunks twisted into spiral forms reaching impossibly high, branches intertwining into spiral archways and bridges between buildings, horrified human faces frozen mid-scream emerging from the bark, residents in various stages of merging with the trees their limbs slowly becoming wood and spiral grain, roots erupting through cobblestone streets in spiral patterns dragging victims downward, bioluminescent spiral fungi lighting the dark canopy above, oppressive claustrophobic atmosphere, Junji Ito manga horror aesthetic, extreme detail, monochromatic green-black palette, two tiny unaffected human figures in foreground for scale
