HELP properly lighting an indoor scene

Recently, I’ve been trying out some indoor scenes, however I quickly came across a few issues with the lighting. I’m only used to photo-realistic outdoor scenes, and have yet to get a well-lit indoor one. I’m using a window as the scource of light, and no lighting within the room itself. Can someone give me some tips for getting the lighting to look realistic? I have vast experience with blender, so I will understand any tips you give me, I just need a nudge in the right direction with photo-realistic, indoor lighting.
