joooowan, I would let the sun fall a little more. You're capturing the twilight when it's too bright. Wait until your window lights are bright enough to match outside.
Also, I'm not a huge fan of virtual tours. This could be because I don't do them and don't want to, and am completely biased about it. I feel like it takes away the artistic side of it, and also gives too much of a look at the inside of a property. I feel like well created photos leave more desired to see, and actually get people in the door. From here, they're going to get a lot more from seeing the inside in person than if they could see it from a virtual tour. They're more convenient for homebuyers, and less for photographers (in my opinion).
