Troll in a Portal Chamber — Watercolor Dream

A hulking troll with mossy green skin, gnarly tusks, and curling horns stands inside an ancient portal chamber. The chamber is carved from weathered stone with rune-inscribed pillars and a central swirling portal that glows with iridescent blues, purples, and emerald greens. Watercolor style with soft washes, feathered edges, subtle color bleeds, and visible paper texture. Light spills from the portal, casting cool blue-violet light on the troll and warm amber highlights on the stone. Mist pools on the floor; vines creep along the walls. The perspective is slightly low-angle to emphasize the troll's bulk, conveying a sense of awe, curiosity, or reverence. The scene is dreamlike and mythical, like a traditional watercolor illustration or concept art.
