Castle under aurora skies in anime fields

An expansive fantasy castle perched on rolling emerald fields under an aurora-filled night sky, drawn in vibrant anime style. The castle features tall spires, ornate arches, glowing windows, and fluttering banners. The northern lights sweep in ribbons of green, pink, and violet, casting iridescent light on the castle and the swaying grasses. In the foreground, wildflowers glimmer in the magical glow while a winding path leads toward the majestic fortress. Crisp linework, cel-shaded shading, lush colors, and a dreamy, cinematic atmosphere.
