@Kingsley36 I'm new to airbnb so I don't know how much help I am but I love to decorate and look at BnB's 🙂 Your place looks nice and tidy and has all the basic needs. If I were coming to stay I feel like it might be nice to see where I would be entering. It also would be nice to know how the area is separate from the main house. I would also add any written information you can to all your photos boxes. That may give people the feeling of security and privacy before booking.
If you are feeling like you want to add any updates to your place, I think floor length curtains attached to the top of your basement windows would add privacy but also make the room look larger and warm. Take the bed and center it between the two curtains. Take the picture you have there and put it in the laundry room on the large tiled wall to add alittle something to that wall. Maybe add a nice piece of wood to the shelf where the furnace bumps out in the living area and add a nice picture. Lastly, you could touch up the paint in the bathroom and around the doorway going into the bathroom to freshen it up!
Maybe this will help?
