I am a bit of a stickler for detail, if it wouldnt be too much trouble perhaps some tools hanging on the wall would add some atmosphere and slight nuances. Also a half finished piece of armor, or a band around a wagon wheel, things that would be laying around a regular workshop 
Just a thought, then again sometimes i get too engrossed in the details of a project and never finish it cuz there is so much stuff to do hehehe... Well thats my 2 more cents -Imp
