First Screen: just stunning...
Second Screen: outstanding!
Third Screen: Impressive!
They all look wonderful!
You have put a lot of work into this level, undoubtedly! Have you read the Online Community Guide by Nickydude? (It should be in your "Docs" folder under the FPSC folder). Your work looks like something of a seasoned FPSC-user pro! The lighting is beautiful. Where on earth did you get that skybox?
Suggestions: I suggest you try to make the meeting room with a low ceiling (contrary to Xplosys). When I think of conference rooms, I think of something long, but short. The second screen shot you have gives me the feeling that it is sort of like an Auditorium.
I would not add boxes, pipes, etc. If this is a meeting room, then it should look like a meeting room (as it does in your first and second screenshots), not like a cargo hold.
Also, I suggest you add some neat-looking hallways and have the maintenance section of your map off-shoot from one of the halls. When I am playing a game and I walk directly from a very hospitable environment into one not so much... it gives an unbelieving feeling.
People have to walk through THIS to get to this room? is what I think. Of course, if there's a story behind that, then leave that way!
Sorry if I appear overly-critical, just me with my thinking cap on.
You have an unusual attention to detail, especially for using FPSC for only 2 months. Have you had previous game development experience in the past?
Is this a
STAR WARS inspiried game? "Research Guild" sounds
STAR WARS-ish. It looks like it! I am a big fan of the movies and TV series. Glad to see another fan here on the forums.
Oh, and your english is great. As long as we understand what you're saying, we are happy. What is your native language, if you don't mind me asking. It won't hurt my feelings if you decline the question.
Good work!

EDIT
I just realized I didn't answer your question. Sorry about that! Your amazing screen shots made me forget

When you say desaturate your light colors, do you mean to make the colors not so strong? Sorry for the rather dumb question, my brain is tired.
One of the most humbling days in your life will be the day you discover you AREN'T the best at what you love to do.
