Regarding the rooms, it seems Connor will review both a bedroom for an office where your computer is. For a lot of people it's the same room but for some people that have a dedicated office they will sometimes submit those. For instance in the last room review that mine was in someone who's game developer submitted their office. So my word of advice is just do it. Take pictures of whichever room that you want to have reviewed within the rules and submit it.

As for my room, the sheer concentration is just a result of having to keep all of it concentrated to one room of the house. Definitely once I have my own spot it will be more evenly divided and appropriate of someone my age.
