Im not sure what sort of an atmosphere your trying to acheive with that model (and yes, even ONE model can totally change the atmosphere), but it looks waaay to clean. I have never seen an armory (which would obviously go through lots of wear and tear) look so flat and clean. Try adding a bit of grunge to the textures and maybe some scratches or dents. This would really add atmosphere to the model.
Not trying to be harsh, but I really think that could you could be a little more creative with this. OR you could go my usual route and create more than one version (clean, grungy, etc.) so the end user doesnt have to make their own.
NOTE: These are just suggestions DR, only trying to help you get better!
