There's a firestorm of morons in this thread.
My input:
Good effort but it could be better. Use less bricks, but don't lessen detail. As a matter of fact, add as much detail as you can without it looking ridiculous. In an airport lobby, ceilings are usually very high. Try looking at some pictures of real airports for more inspiration, and look at some diagrams / blue prints for a generalized structure. Don't make the rooms boxy, like it's a bunch of cardboard boxes put together, make some nice curvy edges and slanted supports / walls, and make it much bigger for an airport-y feel, and add different colors rather than a few shades of grey. Remember, the more effort and time you put in, the more you get out.
Overall, nice effort. Building, not as much.
Don't take any of this as insulting, it's just constructive criticism to help you later on.
