Have you heard of this common model railroading quote: “there’s no such thing as a completed model railroad”- IIRC because there’s always something to improve.
Yep, stop motion has its wonders. I'm into the old Schabaks for stop motion, here's a rough draft: https://www.youtube.com/watch?v=zGp9pR_PpyE
Photo shoots are great ways to learn how airports operate. GSE parks here for this aircraft, there for another, etc. I know some great dioramas of which I can just stare at the photos for hours, and always leave me hungry for more.
Don’t forget that constructed criticism helps sharpen modeling skills too.
However, I get most of the joy from building the diorama itself. The 1:600 1969/70 SFO layout has been under construction for over a year and I am continuously modifying it to mimic the prototype, which is the goal for dioramas based on real life. I guess you can say I'm acting like the real SFO in which there's always something being modified or built. I could give you a big fat list of renovations between the eras I like to model.
One day I'll finish but for me it's about the journey. ETA 2020!
