It is a difficult balance you need to walk to pull off this rendering because it is a bar and it is suppost to be dark. The trick is to keep seating area dark, but focus light on tables where drinks would be and then use underlighting like at the bar and behind the bar back wall.
For the most part it looks like you have good content, we just can't see it or comment on it.
Some texturing isn't very appealing, some of what I assume is concrete looks like it has exposed spray on fireproofing on it and the white wall looks like it has popcorn ceiling treatment.
A few more tweaks and I think you can pull it off
