Any input?

For such a bright sky and bright ground, the underneath of the roof isn't getting much bounce light, maybe try the linear workflow or do some colour mapping to lighten the shadow areas a little? Also the overall brightness of the image is quite even - maybe make the sky a bit darker overall and fade towards the top into a night sky?

This just needs a few small tweaks to make it really nice

Looks good. In my opionion, the interior should be much brighter.

nice render. been trying to do that also. interior can be brighter though.

With linear workflow you mean the linear multiplier in the color mapping? INcrease the dark multiplier? I often have problems getting light in these areas.
