Hey man, it's looking good. The support piece on on the left looks really low res compared to the rest. I would think about pushing the detail more in your high poly, add more cutlines, make the bevels more apparent. Tone down your scratches and put them in areas that would make more sense. Add more grunge on the floor, wear dirt, it should feel like people walk around this hallway a lot. Also, maybe adjust your lighting and tweak your AO.
