So I’m in no way shape or form a builder, and I well cant really build. Besides that, I have no clue what to add to this airport building. People cannot interact with it whatsoever (and I dont want them to be able to, less lag is my main goal here) but theres really just nothing!
You should look up some real airport pictures to copy off of. You have nothing in the inside. You should add a parking lot. The whole building looks pretty bland, like I said before, use real airport pictures as references.
In my opinion the sides of the building and the roof are extremely flat and bland. You can add in details like overhangs and stuff to spruce that up a bit. As far as the outside goes you could do a parking lot, air traffic control tower, and other airport-related stuff to give it a more realistic feel. I would definitely recommend looking up some reference pictures though.
I can’t really judge (sorry). There isn’t much there too judge. The windows could be less reflective and add more stuff like vegetation and a entrance maybe?
So the basic rundown of my opinion on this build is that it’s way too much glass, there’s no supports holding anything in place either. The roof is also rather odd and nothing about the building really screams “airport”.
Some things to consider.
The glass shouldn’t stick out, instead the frames around the glass should.
Less glass in general, make the door more detailed.
Roof is very weird, try something smoother.
Base your design off existing airports.
Consider the additional bits around airports, such as canopies at the front, signs, etc.
Generally airports are rather curvy, wavy structures with thin sleek designs nowadays, so that shouts “airport” more.
There would definitely should be the gates where people would get to the plane, the areas where planes get fueled and get ready for takeoff. Some planes next to the building with the passage ways to the planes could be really awesome. Good luck!
