The graphics seem great for the scale, but it seems that when you get close (at least your screenshots) it doesn't have that much detail and textures are simple (both understandable due to the size of the simulation).
Yep, lower than 200 feet and it starts getting pretty rough. The grass next to the runway looks pretty good but building textures are plain.
It's night time now
Landing at night, street lights are nothing but floating light points. Looks great from 200 feet up, rough from the ground. It's a flight sim, not ready for truck simulator (yet)
