Watercolor Troll in Damp Underground Tunnels

An atmospheric watercolor illustration of a hulking troll standing in a damp underground tunnel. Warm amber lantern light flickers from a hanging lamp, casting long, smoky shadows on wet stone walls. The scene uses soft washes and color bleeds typical of watercolor on rough textured paper, with gentle edge diffusion and subtle granulation. The troll has rough green-brown skin, warty texture, shaggy mossy hair, bright yellow eyes, and crooked tusks. He wears ragged earth-toned clothing and carries a worn burlap sack. Surrounding the tunnel are damp surfaces, moss patches, puddles reflecting light, and stalagmites rising from the floor. Bioluminescent fungi along a crack emit a pale blue-green glow, adding an eerie touch. The composition shows a three-quarter view from the left, with the tunnel receding into darkness behind him, creating depth and mystery. The mood is enigmatic and fantastical, suitable for a fantasy setting.
