Shadow Creature in a Watercolor School Corridor

An eerie watercolor scene inside a quiet school: a shadow creature, amorphous and ink-black, drifts through a sunlit corridor. It is a formless silhouette with curling, smoke-like tendrils that wrap around old wooden desks and hover near a chalkboard. The edges bleed and blend into the pale walls with soft wet-on-wet washes, while navy, slate, and lavender gradients swirl with warm yellow light from high windows. The hallway is empty—lockers line the walls, a row of desks, a faint clock, and dust motes drifting in rays of light. The creature has no solid features, perhaps a pair of tiny ember eyes or a faint inner glow, giving a calm yet unsettling presence that swallows light rather than blocking it. Use loose brushstrokes, barely defined forms, and color bleeding to create a dreamlike mood. The composition can be from the corner of a classroom looking toward the corridor or from a doorway as the shadow glides by.
