I’ve looked at several houses and thought but they have no stuff. Where would my books go, could you get a computer and digital piano in here. I’ve even seen kitchens with no toaster or music crowave and thought is there room/ enough plug points.
That is why you 'dress' the house to suggest how the areas can be used.
A microwave, blender, toaster on the counter, yes - but not piles of paperwork from school or visible bins that would suggest lack of space. A plant on the counter to suggest that natural light is a feature and that a kitchen is so spacious that there are square inches to spare for something that isn't purely functional.
A plant and a candle or two in the bathroom to suggest the same and also to convey a sense that your bathroom is a place to relax.
Dressing the house with suggestion in mind is better than leaving it exactly as you are using it for the photos because you can appeal to a broad range of tastes when you create little scenes using your belongings as props.
People who like books and people who like space will both find a well arranged bookshelf pleasing. People who like cooking and people who like a clean, neat kitchen with lots of counter space will like a kitchen where the usefulness of various zones is suggested and the rest is clear and clean.
Most people who are moving house are looking for more space or somewhere they can comfortably downsize to, so it's always a good thing to minimise the amount of your own stuff that is visible and maximise the suggestion of spaciousness when selling.
People all over the world can see your photos. You do not know where a potential buyer might be coming from. Therefore the idea that people where you live are expecting to see china figurines is a bit 
I would redo the bookshelves. Put a few more books back, both vertically and horizontally. Use big books. The box (?) in blue with the three houses on it needs to be on the bottom shelf to anchor the tableau. Get rid of those figurines - bring them to your mother's house if their value might be jeopardised in a shed or commercial storage space.
There is nothing you can do about the pianos and equipment - but don't leave any paperwork out for the photos. Gather it up and move it to another room. You will be scurrying back and forth a but but it will be worth it.
You are trying to sell something based on a first impression and that impression is completely visual. So you have to pay attention to the impression that little details are conveying.
