Young girl by frosted window with Christmas hot chocolate

A young girl stands by a window, the frost creating whimsical winter patterns on the glass. Her hair is slightly tousled and she's just gotten out of bed. She's wearing a short, spaghetti-strap Christmas tank top and shorts, and she's barefoot. She's holding a mug of hot chocolate with marshmallows. In the background is a cozy room, a sofa, two armchairs, and a breakfast table, with a decorated Christmas tree in the corner. This welcoming, bright, and gentle illustration is created using digital watercolor.
