Haven't read the full thread but I actually quite like the look of your house from the outside.
The things I would mention are what everyone else has said, pick a sunny day to have the photos taken, all those lights on makes it feel dark.
Personally if I bought the house that living room carpet would be the first thing to but it wouldn't put me off buying.
Remove the photo of the garden looking into other properties as it just screams 'these are all the people who can see into your garden and house'
The lack of pictures on the walls makes the house feel unloved. Like it has no personality. So I would be getting some picture up, especially in the living room to help distract from the massive Tv.
Also, plants and fresh flowers help. I notice you have some plants in the dining room but none anywhere else.
So really, I think if you just 'dress' the place up a bit, it will really help for the photos and viewings.
