Your decor is pretty sterile. I see your EA made you do that - I would replace your plants everywhere and your pictures too, if they're like your DR pictures.
You need new photos. The current ones are not flattering.
You also need room dimensions on your floorplans. This is extremely important.
I would redo your beige living room.
If I bought your house, the first thing I would do is take out the grey carpet from the living room/dining room. If you can't do this, then repaint the walls in a light colour - off white or pale cream.
You should find a fairly large, light coloured area rug to cover up the carpet as much as possible. I suspect it's contributing to the impression of a house without much natural light.
I would take down the short, dark curtains from the front window too. You need long ones there, in a light colour, to enhance the light and to lend an air of comfort.
The fabric couch in the living room has too many cushions on it and it is bunged into the corner. Pull it away from the corner. Lose the pink cushions. Pink is a very random colour in that room. Maybe put them on your bed? I would be tempted to get rid of the dark cushions too and replace with with light coloured ones, or something bright like coral/orange. If you were to put the long burnt orange (?) curtains from the DR into the front window you could use hints of the same colours in cushions, throw rugs.
For photo purposes I would put the ottoman in front of the fabric covered couch with a nice light coloured throw blanket folded/draped on top.
Put the coffee table in front of the other couch. Dress it up with a tray, teapot, mug, and a little stack of books. Put a candle there too.
Put a nice white or cream throw blanket on the second couch that is now returned to the living room.
I would put a tall plant in the living room, maybe in the corner where the standard lamp is now, and put the standard lamp by the couch (in the spot you will free up when you pull the couch out a bit). You could buy or borrow a nice big plant or even a silk plant for the purposes of photos.
You need newly washed plush-looking towels (the pink is nice) folded nicely on the towel rack.
Plus more photo angles in that bathroom. A nice big candle, some expensive toiletries too, as the black/white decor is a bit austere.
Take the rug out of the lilac room. Don't replace it.
Take the small white chest of drawers out of the yellow room. Put it in storage.
Replace the short grey curtains in the master bedroom with floor length white or very light cream curtains, which will suggest comfort, softness. Get a few more decorative pillows for the bed. The pink one is nice but it needs a few friends.
Your bedroom needs a few personal touches - candles, a nice plant, a picture or two on the walls, a stack of books on the bedside table.
Is that a BBQ area/ pizza oven at the bottom of the garden? If so, need photos.
I would place some nice outdoor dining furniture on the paved area after power washing the slabs.
The house is lovely, as is the garden. Very well kept.
