Hi OP, it must be awful to be so heavily critiqued. I do think it's quite cold and bare at the mo - all walls are white and floors are all laminate. All the seating is a bold colour, and hard fabric. It's not a space you can see anywhere to relax.
The layout is unclear from pics. It took me ages to work out that the lounge and kitchen aren't the same space, so it needs redefining as a place to live.
Lounge: Get a larger mirror with a frame to match dining table, the current mirror is lost.
I would move the red chair further into the room (to roughly where your rug finishes now) and add a warm-toned coffee table between that and the sofa. You should then have a more squared off, defined living space.
Lose the green rug, it adds nothing. Get a thicker textured rug to add warmth (B&Q has a nice neutral one called Noelia).
Move dining table into a prominent spot in front of window instead of seemingly hidden away behind the entrance as you come in.
Kitchen: hide stools, they look cold. Vase of flowers on the island. Large statement clock on that wall. B&Q has a gorgeous subtle paint colour called Colour Courage soft grey, I think it could really warm up that wall (and would probably transform your lounge if you'd put that on instead of the wallpaper).
Main bedroom needs a more neutral, luxurious bedding set.
Hanging basket outside. Take car off drive.
I think it's very spacious and bright so some minor inexpensive tweaks could make a huge difference. Have a play with your furniture. And think mirrors, flowers! And change that rug! Good luck
