Very nice!! Did you also try to put arealights in front of your window? It gives a nice daylight in your room!

My new trick is not to use HDRI, but a sphere with a solid material. I use a sky jpeg for the texture. This gives more control over your sky and the illumination of interiors is much better than with an HDRI.
