Starry Fortress in a Watercolor Night

Watercolor illustration of a grand medieval fortress at night, stone towers and crenellated walls rendered in soft blues and grays with mossy greens. A starry sky looms above, featuring a luminous gold star that hangs low behind the fortress, its glow spilling across the walls and reflecting in a calm moat. Use classic watercolor textures: wet-on-wet washes, feathered edges, gentle color bleeds, and light grain. Include subtle star motifs on the fortress—star-shaped windows or banners—to weave the theme into the architecture. Dreamy, magical mood with serene twilight atmosphere.
