Golf course dining room, WIP

This is a wip, it still needs a lot of details but I would like some input on what you think it needs so far.

There is a curtain wall that faces the golf course that cant be seen but the light coming from it can.

Shadows

the tables are casting shadows vertically, as if there was a source on top, but that source cannot be seen, either show that source, or the shadows should point the opposite direction of the curtain wall.

Depth

The ceiling detailing is coming on nicely, but the tables and carpets are lacking somehow. What presets are you using? Maybe uping these to medium or high will improve things - you get much more subtle GI details when you up these settings.
