The agent who has taken the photos needs some help!!!!
The shots are too high up so you are looking down on the room .. up on the corners get a wider shot ...
Leave out the photos of the room with the single beds they are practically up against the wall.
You may also want to consider painting it all out in a neutral colour if you want a good price.
Remove some of the furniture or hire a company that can dress some of the key rooms...
Also I would get rid of the book shelf wallpaper in the toilet.
The garden has lots of potential but could be off putting to buyers...some carefully arranged pots and some nice garden furniture and an umbrella would work wonders there.
The outlook from the garden looks rural??
That's a peaceful selling point.
Also the first photo isn't take straight on.
Take the front of the house photo...maybe even have some pots of flowers and a nice doormat for the photo..
Tell your ex if he wants a good price he needs to act!
Hope that helps.
