I don’t excel at building but I do thought I give it a try as I do want to develop a small game anyways.I don’t mind any criticism as I do need them.Anything you like or dislike,share them.Thank you.
As this is for a game,I am not adding an arrival hall,check-in details or securities,this is just for small game that I want to work on,however I am adding other sorts, so do suggest and I might add it
You can check out the first bits of the airport when I started it right here.
Looks nice! Maybe add more details to the wall and roof, like adding lights, paintings, modern art, etc. From what I see, the ground looks pretty dark from shadows, lights can fix that up quickly.
The inside is okay but pretty basic. I also suggest trying to use textures rather than Roblox Materials. Just the outside needs to look a lot more detailed, as to me it currently looks quite bland and simple. Also, change the grass material to something like Granite (for the block under Check In). Decent start though. 
Looks decent, I’d suggest adding more decoration and overall more detail to the exterior of the airport. It looks so empty without all of these tips. One last thing you should add is lights to the ceiling, good luck!
Your airport looks okay.
Inside you could add the following:
To me it looks like you built this without using a reference.
Use a reference! That is, not to exactly copy from, but to keep you mind flowing with ideas of what kind of details and layout to include.
I feel like the roof should be higher, and instead of the letters spelling “check in” make it some sort of map with a pointing arrow. Maybe I’m asking for too much.
Other than that… good job! I like the screens that show the flights! Keep up the good work!
Perhaps adding a brick border to the “Check-In” hedge might make it more realistic, as it seems to be coming out of the marble ground.
a bit lost,what do you mean,i am not sure?
The hedge under the check in sign, or, we’ll if it is a hedge should try to look like it”s coming out of a wide pot, rather than out of the ground.
