It looks decent so far, The inside looks great the outside lighting could perhaps use a bit of work but it looks good otherwise. However if you want to sell the story behind shady sands (that is is a post apocalyptic settlement) You may want to consider adding additional props in the dining area (such as bottles, cans ect) and the outside looks a little too clean for a place that has supposedly been blasted.
Having a look at shady sands in fallout you can see the buildings have pot marks and cracks presumably from debris from the nuclear blast and perhaps raider attacks. (Don't know the full story of Shady Sands never actually played Fallout 1)
Looking good, just needs more detail to look great.
In my noobish opinion.
