My personal opinion (for what it's worth)
Rearrange the lounge, turn the whole lot around, have chair or sofa in the window alcove and to elsewhere. It's an awkward shaped room and the chair in front of the door makes it look even more awkward/cramped.
The kitchen is very uninspiring. Ok, the units themselves aren't particularly pretty, but it's so bare that I can't imagine anyone cooking a meal in there. It looks unused and therefore unusable.
Bathroom, as others have said have a pic of the shower too.
Re-write of the blurb so that it includes room dimensions and cuts out all the bullshitty sales patter 'deceptively spacious' is merely another way of saying 'compact and bijou' aka tiny, pokey, small.
I think the dad's room os actually the only one with any character and get a photo of the box room/study put in - it's important! There's nothing wrong with a box room, but I find that by not including a pic, you're giving the impression that it's not worth looking at.
Inject a wee bit of personality/comfort/homeliness. You don't have to go mad, but people want to see a home, not a stark box.
Oh, and definitely look at the price.
You either want to sell or you want the higher price. If the former, drop the price as it seems very overpriced for the size and shape of the rooms. If it's the latter, you're on a hiding to nothing as the house won't seek if the price is too high. The fact that you've had no interest tells me that people are being put off when comparing price to photos.
Also, for some reason, EA's lately have gone mad on 'arty' waist height photos which just show corners of rooms. Get them redone, from eye level and in a way which shows the sizes/dimensions of the rooms. And shows the house off in a good light.
All in all I think you've been let down by your EA. perhaps try someone else?
Hav you thought about doing an open house?
