Get them to retake the photos on a sunny day.
Put pot plants/flowers in both front and back garden.
Restage entire house, it looks sad and empty and like the owners are divorcing. You need cushions, frames of the kids, flowers in vases in a few room, stage the kids' bedrooms to look bright & fun.
Next time the photographers are in, hide the bins outside of the garden, your back garden looks like a bin store.
The house is too tidy and too decluttered.
The blinds on the conservatory are awful, the conservatory has not been set up/no focal point.
