I like this approach. You improved the lighting as I can see (I was lucky to see some images before this thread). The models look great and normal maps are fine.

Besides that it needs some improvements:
- the carpet is too bumpy and too shiny
- stones should reflect light in some spots but wood should not

You can add some dishes, golden goblets (with much specularity) and interesting windows to cast some interesting shadows. If you do not have pojection shaders for that then a slightly transparent sprite could help to fake light and shadow coming from a window. Some ray of lights can also be faked throug such a sprite.
