Motivated Lighting
Match the direction and quality of illumination to a light source within the story so the scene's lighting makes sense.
Prompt
Use Motivated Lighting: let the existing large left window motivate the lighting. Daylight from that visible window softly lights the window-facing side of the original character and the existing adjacent desk, with illumination falling away across the room toward the right shelves. Keep all resulting highlights and shadows consistent with this same visible source. The hanging lamp remains off; no added equipment or unexplained light direction. Preserve the original patchwork colors and illustration style.

Effect comparison
In the baseline image, light is distributed relatively evenly around Ruk's studio. Motivated lighting brightens the side of the figure, tabletop, walls and floor facing the left window, while the bookcase farther from the window on the right grows darker. The visible window explains where the light and shadow come from, giving the figure and setting a shared, believable lighting direction.
