I'd agree with cutting the number of photos down, but I think in particular I would be tempted to lose the photos showing the back of the house as IMO they make the house look really overextended. I don't think it gives that impression, especially when you see the neighbours either side.
I don't mind the orange splashback, but I'd lose photo 3 where it totally dominates the picture. Really, cut the kitchen shots right down, there are 10 of them and it's just going to irritate especially as most of them aren't adding anything. I'd probably strip it to photos 2, 5 and 6
I'd try to make the family area feel a bit more like a second living space - I don't think the smallish lounge is necessarily a problem but at the moment the family area just feels like a big sofa parked in your kitchen. Actually, I think if it was me I'd be tempted to have the family area with a (more modern) dining table in it, and the dining area as a family sitting space so it feels more like there are two distinct sitting spaces which would be more suitable for a house of that size. If that won't work then I'd get a rug down, maybe a coffee table or footstool in front of the sofa. I'd also put some sort of runner in the hall - I find the vast expanse of tiled floor very cold and offputting, I think you need to break it up so it's less of a dominating feature.
Dining area feels like a bit of an odd mish-mash; old piano, antiquey chairs, and a bunch of ikea stuff. It just isn't working IMO.
The duck egg blue bedroom - I'd try to dress the bed more, get some cushions etc in. Photos 12 and 13 are more than enough though.
I'd say photos 26-36 are all unnecessary and just confusing - I agree with trying to order them so there is a flow to the house too.
