Agree with rearranging the small bedroom, take out the desk, put the bed in different place, make it look cosy not cramped. There's another photo (no 10/17) and I can't even work out which space in the house that is. The rail of clothes looks awful, why would you even have that photo included?
Bathroom looks like it's a very tight squeeze between the sink and the shower screen to get into the bath / shower. Maybe perspective, but it's not a good photo. The toilet seat does not match the shape of the toilet. Relatively small point but it is just another thing I'd have to sort if I bought the house. And the kind of small job that is a pita.
Remove the green bin from the kitchen photos. It completely detracts from clean lines, and makes me think there is no proper place for a rubbish bin. Let them work that out for themselves, don't show it in the photos.
Your back garden is pretty scruffy. No colourful flowers, dead plants, patchy grass, no obvious welcoming seating area or patio with fairy lights, or any of that crap.
In general I don't think the photos are well taken, they should show your house off to the best. If they were taken by your estate agent I'd ask for them to be re-done by someone else.
But the thing that would really put me off is the entrance, and the photo. It took me ages to work out what was your house, and your entrance. The large shared monoblock would ring alarm bells. You need a clear demarkation between your property and the next door neighbours. I'd imagine that ndn might park on on over your space. You need pot plants, colour, greenery to make it look welcoming. You need a clear path to your front door - and clear demarkation from the neighbour on the other side. Your door to your neighbour's house looks terrible, it would make me wonder what they were like... I'd offer to have it painted for them (at my own expense) so that the whole neighbourhood looks improved and well cared for.
Sorry, I have been harsh.
