mmmmm. All of this is lookin pretty nice. A minor crit on the chair though. The wheels seem to have a pretty high spec value. I'd think that since theyd be rolling around in this public place all the time, they'd pick up a bit of lint, dirt, etc. 3k Tris also seems like a bit much. You could definitely take some out of the metal area when the chair connects.
I think you should do some observation research when it comes to some of the materials. You have great stuff but it falls short due to the specs and diffuses. The hatchet for example looks great as a sculpt but looses a lot of readability when you have the textures applied, there's a lot of noise on the metal.
use your photo ref as a starting point and nothing else. Don't depend on them too much. i say this from my own experiences.
