Create a sketch-style rendering of a playful and cozy child’s bedroom for a young girl. The room should feature a small bed with colorful bedding in soft pastels like pink, lavender, or mint green, with fun pillows and a stuffed animal resting on it. Include a small bookshelf filled with children's books and toys, along with a toy chest at the foot of the bed. Add a cute little desk for coloring or crafts, with a chair in a matching color scheme. The walls should have playful elements, like decals of butterflies, rainbows, or stars, and perhaps a growth chart. Add a soft, round rug in the center of the room and a window with whimsical curtains letting in natural light. The space should feel bright, cheerful, and full of charm.
