Create an image of a serene coastal-style bathroom and adjoining bedroom, bathed in soft, natural light streaming through large windows. The bathroom features whitewashed wooden walls, a freestanding clawfoot bathtub, and a weathered wooden vanity with a porcelain sink. Hints of seafoam green and sandy beige accents create a calming atmosphere. The bedroom boasts a light, airy feel with a white linen-draped bed, driftwood accents, and sheer curtains gently swaying in a subtle breeze. As dusk approaches, introduce warm, ambient artificial lighting from pendant lights and sconces, casting gentle shadows and enhancing the room's cozy, inviting ambiance. Capture the essence of a tranquil coastal retreat, blending natural and artificial light to evoke a sense of peaceful relaxation.
