Done with overtime!

A chibi-style anime girl with long, messy black hair is sitting on an office chair, holding her arms up in a tired and happy gesture. Her eyes are closed, and she has a happy but tired expression on her face, with a relaxed smile and a slight blush on her cheeks. She has bags under her eyes. She is wearing a black formal suit with a tie, black pants, and black shoes. The office setting is modern, with a gray office chair, a desk with a computer monitor and keyboard, and a window showing a cityscape at night with tall buildings and a few stars. The lighting is perfect, with a combination of soft, warm artificial light from the desk lamp and the cool, ambient light of the cityscape outside. The atmosphere is one of exhaustion mixed with a sense of accomplishment and relief. The style of the image is an ultra-detailed, extremely delicate, and super fine illustration, with a focus on creating a sense of cuteness, depth, and mood. The angle is dynamic, capturing the girl from a slightly low perspective.
