It looks really nice.
Could you possibly add a photo of the living room without the rug down? It's quite bold so it stands out, but it presumably won't be staying. If the carpet under it is nice, it might be worth showing that off a bit.
I would swap the kitchen photo for one that doesn't include the washing machine bit - I'm sure it looks fine IRL but in the photo it looks a bit clumsy, perhaps like the kitchen is too small for your needs. I'd be better not to have the boiler in the photo as well.
For photos and viewings I'd take down the tent things on the kids' beds.
It would be nice if you could get a better photo of the front - zoomed in a bit closer to show just your house. Maybe put some flowers on the balcony, even a little table and chairs if you could borrow one/buy one cheap.
Any chance of photos of the bathroom and downstairs loo? Even if you could make it a photo of the hallway with the door open into the bathroom it'd give people an idea.
Is there a dining area or could you make one - borrow a 2-person table and chairs and make a little room in the living room perhaps?
I'd get your agent to add a floor plan too - when we were looking I felt like I needed one to see if the house would work for us.
