Get the photos retaken and put a duvet on your bed, we are going into October so why use photos from May when it was hot as you stated previously?
Identify who you are selling to - a couple, couple with 1 child who will when child number two arrives move? Aim at your target buyers and make them want to view from the photos and then hook them in on the viewings with nice smells, subtle classical music playing on low and an indulgent this house is special feeling.
Cosy, welcoming and a sanctuary from Covid etc needs to be the feeling that the house gives.
Look on marketplace for a double bed for bedroom 2, if you don’t want to keep it once sold you can donate it to a good cause.
People are inherently curious about the people who live in a property and whom they are potentially buying from so paint a picture.
The Lakes you mention, presumably are outdoor beauty spots so use this and have books on display which suggest a virtuous weekend spent walking/cycling in the great outdoors etc to then return to a warm and welcoming house with cosy not stark lighting, some texture on the sofa - a throw to curl up with a good book and a glass of wine. Where are all your books!?
Bedroom 3 which is a dumping ground for a dispirit collection of ‘stuff’ needs tackling.
Shed in the garden or a hired storage unit could provide storage for the day bed and contents of bed 3 and the bin.
This needs effort and planning to make it compete against the other houses available.
