Edit this existing image to add a third clear glass of water on the wooden table. The image currently shows a cosy study scene with open books, notepads, pencils, and two glasses of water — one on the left near an open book, and one on the right in the background. Add a third clear glass of water somewhere naturally on the table. Keep everything else completely identical — all books, notepads, pencils, eyeglasses, the bookshelf, the chair with a blanket, the plant, and the window light must remain exactly as they are. Photorealistic, warm lighting, not a cartoon or drawing.
