God you lot are vultures 
Sorry for not replying to individual comments but I'll do my best to reply to what has stood out to me.
Price I do think it's fairly priced. It's actually 10k below what we originally went out at. We are the cheapest of all the same style houses in the area. But of course if it won't sell then I need to consider price.
Colour I did think this would be an issue. The red room is an easy fix. I will definitely consider painting the green room. It does look bright in the photo, it's really not that bright. I'm glad most people like upstairs! I am not re tiling the entire kitchen, my god it's massive and would be a huge expense!!
Layout I hadn't even considered this and a lot of you are saying it. When it's your house it just seems normal! We have it that way around because of ease, it's easy to watch the kids when I'm in the kitchen. But also the front room doesn't have an easy layout to get much furniture into it. With the fireplace and the radiator and also the two doors create a corridor effect. But I hadn't thought of swapping them, definitely something we need to talk about. We would have to put some bits in storage, again something I hadn't considered.
The green room ha ha at so many of you calling it that. We have to have a desk for my husband and it's the only way to have both desk and dining table in there. We don't actually use the dining table because we eat at the kitchen table. I see what you all mean though that it's not inviting. The fireplace has lights in it hence the 'glow' although I do wish it did go to narnia 😂
Garden we did have a photo of the back of the house but it's a flat room extension so the agent removed it as they thought it might put people off. We do have pots and a table and chairs out there.
Anything else...erm yes the chair in the nursery is very much in use. Someone mentioned clutter? I literally removed so much stuff for those photos!! I'm not sure how much more I could remove?
Did I miss anything major?
Thank you everyone, it's so helpful to get an outside perspective. Everyone we know says it's fine. Which clearly it isn't because it hasn't sold.
