Not a bad start.
Some of your pillars (first image, just left of mid) have horizontal wood texturing, that looks really weird. Rotate that 90degs to look more like a solid, single piece of wood on end, not a layered cake of wood. (You do this in some other areas, like the door frame).
Also, your posters/pictures are kind of really big or just, not really in good spots. Why would there be a HUGE mountknife back poster all the way up there? Those are usually smaller and lower. Alos, the employee of the month picture is definitely too big. Those are usually a bit smaller. (unless thats a prop, in which case I still think it's too big).
Also, the chicken wire scaling is HUGE. Drop that down from .25 to like, .05 or .1. The Chickens could escape through that!
All in all, not a bad start.
