Create a soft pastel painting of a pensive woman gazing out a rain-soaked window. She has long, flowing hair cascading over her shoulders, partially obscured by a gentle cascade of raindrops on the glass. The setting includes hints of a blurred, softly-lit room in the background with delicate shadows. Use a warm colour palette featuring muted pinks, soft blues, and gentle greys. The lighting is ambient and diffused, capturing the serene atmosphere. Incorporate textured brush strokes that evoke a feeling of warmth and introspection. The scene conveys a sense of longing and contemplation, with the rain outside contrasting the warmth within.
