I know people should be able to look past the décor, but that's why newbuild show homes are set up for living rather than just being empty - aspiration innit! We have friends who paid to have their house properly 'dressed' for sale (both working, 2 small children, house by their own admission was a tip). Think it cost them about £2K but they more than made it back and the house sold really quickly.
The main things which jumped out at me are the curtains, lack of pictures and where you have them they're hung too high, and the mismatched furniture. the garden needs tidying/cut back.
First picture - is that a ramp leading up to front door? Can't quite work it out. Garden needs to be tidied and trees pruned. Would also have a better picture showing the front garden.
Back garden needs tidying and lawns mown.
Living room - straighten curtains and drape them equally on either side so they hang nicely and cover the edges of the windows. Hang a few pictures - and hang them at eye level, not high up on the walls. Maybe a rug in front of the fire place.
Dining room, again, curtains need to be properly draped. Bigger dining table in the centre of the room would make the room look better. Pictures - hang at eye level. You could perhaps remove your daughter's toys just for the photos. There are lots of 'bits' of furniture - perhaps one larger bookcase or shelving unit would be more cohesive.
Try and make it look as if the laundry is part of the kitchen - trying to think how you'd do this, maybe some of the same units instead of the cupboard. The kitchen is small, but to me the proximity of the laundry means that wouldn't really matter.
First bedroom pic - again, curtains. Put a valance on the bed base. Hang pics and mirror at eye level and swap the smaller pieces of furniture for one larger piece.
Blue bedroom looks OK if a bit bland.
Child's bedroom - sort curtains, invest in an Ikeas storage solution and get rid of the bits of furniture.
Bathroom looks fine.
Too many pics of back garden.
Picture of fireplace unnecessary.
Cloakroom looks fine.
Would there be room for another kitchen base unit next to the cooker instead of the pan stand or is it in the way of the door?
