Having trouble rendering this interior.

My first approach test001 was using portal lights but that took a long time to render. Or maybe I just had the settings wrong for that render.

render settings had about 12 portal lights
set to direct lighting with 32 samples

an environment light set to raytrace background
with a few area and spot lights.

2nd approach test002
I killed all the portal lights
have an env light set to raytracke background
just have spot and area lights

then I did a third render test003
and after this one I felt stuck.
tried adding a bounce light with area light and I just didn't get the result I wanted.

rop settings
pixel samples 4 x 4
color limit 5
reflet / refract 5
direct lighting as color

tried adding a GI light and that doesn't seem to help either.

I know overall shaders need work, but just wondering what I'm doing wrong here.
