Update! This is the current progress, mostly done, and waiting for smaller details. I also plan on making the ground look more rough and imperfect, as real-life airports usually have mismatching concrete colours and seams, etc.
I am really happy with the design choice for the terminal building.
Looking south-east from the north terminal section (1920x1080 resolution)
Identical to the image in my first post, just improved!
This project will probably take a couple more months for completion.
