For 2.5 million I would want a virtual tour or video, and not one of those collage of all photo videos, an actual walk through. I see them on 350k houses so it feels tight not to get them on a home of your value.
I would re order the garden photos so you see the biggest garden bits before the smaller ones.
Labelling on photos also helps, bedroom 1, garden, annexe garden, utility etc.
Lifestyle? No, I don't want close ups of bannisters, oranges or taps, but photos from each angle of each room are especially useful, I want to see exactly how much room there is at the end of a bed and to both sides.
Lovely home, good luck with the sale!
