I bet your home is lovely OP but the pictures aren't telling it.
There's nothing which makes me think 'ooh I'd like to live there'. But the three pictures you posted all make me think 'ooh'. I
I think your biggest 'wow factor' is the terrace overlooking the park. The picture of the terrace on Rightmove is largely of an uninspiring white wall and totally fails to capitalise on your views over the park. Stage this area up - paint the fence and furniture, pimp up the plants and you have your 'wow factor'. If you had really good shot of this I'd make it your cover photo.
Relatedly - not at all obvious without studying the floor plan that your kitchen has french doors out to the terrace - the angle of the photo and the location of the kitchen table totally obscures this (I thought it was a normal window) - you've got the potential for people to be able to imagine themselves taking their coffee and croissant out into their terrace with the lovely peaceful views and it's an opportunity totally missed. I'd be inclined to paint the wooden surrounds on the kitchen units to match the doors as it looks dated.
I know you say you decluttered for the photos but it looks like you might have focused on the wrong clutter! It manages to look a bit stark and not 'homely' and yet still look a bit cramped and full.
Living room - I'd get at least two of your bookshelves into storage and replace with some nice simple side tables with a lamp, vase of flowers etc. Plain rug in the middle of the room. A picture on the wall.
Bedrooms would benefit from better staging. Fans and uplighters etc off into storage.
Bathroom - been said lots but needs colour! Unless you can get a much better photo I'd omit it from the set as it's currently offputting.
