I generally tend to agree, but I look at something like FlyTampa’s KBOS or Drziewicki’s KDCA to see beautifully modeled airports with nice interiors (great interiors for DCA!) that perform really well on my system.
But generally yes, I’d rather see texture improvements on the buildings, and the addition of some things like branding on the new airport hotel (which is modeled) and the addition of the Tower and an AFCAD so some cargo planes would spawn over at the FedEx ramp and airliners would be where they ought to be with FSLTL or FS Traffic.
