looks good dude. I like the details but I think you need to pick if its going to be clean or weathered.
Wood grain looks really flat all around. When you do your crazy bump pass try and push the wood grain more. Try and do an overlay with some real wood or add just a bit of noise. Looks like your going for a pretty weathered look. Keep pushing that throughout.
AO on your wall texture around the lower detail looks to strong. Not sure if its painted or baked but seems like it could use a softer gradient.
anyway just some quick thoughts.. getting back to my project
