Looks good to me. The strange thing is you can't have blown out daylight / sun and shadow and still get interior lights. You have to live with the fact that this is not realistic - or turn down / off one or the other. The soft light from the window looks good!

It's a good start. Too much ambient / even light. Textures could use some work. Watch the texture scale / tile repeats. More reflections. The wide-angle camera doesn't help. Good Luck!

Nice Work!
