Hello, @elexotus !
Your exterior on a first look, is looking great, but things can be improved.
As you’re making an airport, I assume you’re working on the building in a realistic style.
So I think I can help you with some advices.
I think you can improve the road, it feels quite empty, split it in half, and make whatever you want, a parking, or path for people to walk on, but something is missing for me.
Also, the roof seems to fly, try to add pillars, or something to hold it, it feels like it could fall apart at any moment.
The sign is quite empty too, add lighting, and maybe more writings, something to make it more alive.
And last but not least, add more assets, just to make the exterior real, it’s really important to have a full environment, it’s more important than a giant empty exterior
I won’t talk about the interior, but I would tell you some similarities, improve the lives of your creations, but it’s a great start, that can lead to a great build, You can check on the small awful draw I made, maybe it will give you ideas.
