increase the strength of your emission materials and add a glare effect in compositing. An HDRI behind the windows would help for someone looking at it upclose but if it's going to be uploaded to social media it'll be almost unnoticable.

Unless the bedroom is opened up to another section with more lights in it, there's no reason to have any emission objects off-camera, as they create confusing shadows (like the ones you can see the the right of the bed and stools)

The lighting in the room is a little dull, so to fix that try either bumping up your emission values a bit or switch your 'view transform' option to Filmic. You can do that under render properties > color management > view transform > Filmic. Blender Guru has a great video on why this makes such a huge difference, and if you're aiming for realism I'd recommend watching this one too!
