add a fairly large substantial armchair positioned in the upper left corner of the image the armchair itself should be large in scale with realistic proportions of a full size lounge armchair but only a small fragment of it should be visible within the frame part of the seat one armrest and a section of one leg the rest of the armchair should extend naturally outside the frame the visible fragment should feel close to the camera and appropriately large not like a small miniature chair or distant piece of furniture use rich warm orange upholstery with clearly visible soft plush slightly padded fabric and realistic textile texture the upholstery should look soft comfortable and tactile the armchair leg should create a soft realistic light shadow effect on the floor naturally matching the existing lighting direction and perspective important preserve the entire existing visualization exactly as it is do not change the architecture furniture materials colors floor walls doors lighting camera position framing proportions or any other element only add the large armchair fragment in the upper left corner
