Realistic Room Promotion Render from Sketch

Create a real-life room promotional image to market my room to potential tenants. The theme is room layout: a large floor-to-ceiling window on the left with excellent sunlight and lighting. Beside the window is a cat bed with a {argument name="pet" default="orange cat"} lying on it. Inside the bedroom is a large desk with daily items like a computer, keyboard, mouse, and phone. A young Chinese male is sitting on an ergonomic chair operating the computer. To the right of the desk is a single bed. The overall spatial relationship follows the sketch. Lighting and textures should look like a bedroom photo taken with a phone. Hard requirements: all items drawn in the sketch must appear, including the sun outside the window. Problems to avoid: do not include any elements or phenomena that contradict real daily life. Other proportions and room details are up to you to ensure a natural, realistic, and unforced effect.
