Just Wow! Very impressive work. It's way beyond what I want to do (or can do) at age 66. But it is wonderful to look at and it can give one ideas for a few "extras". If I give this a "100" for details and extras, I am probably thinking of maybe "12 - 15" for what I'm doing for fun (and to preserve a little NASCAR history from 45 - 55 years ago).
We each have our own ideas and goals, I am glad that you can do this so well. (I just worry about mundane little things such as where to find dirt-track tires and the right headers for a 1966 Fairlane or cowl-induction air cleaners for other projects.)
I have other interests indoors and out, such as nature photography, building front yard rock gardens, tending native plants, mineral collecting, light indoor carpentry, … aside from my planned model building. [My second wife is a retired Occupational Therapist and she makes jewelry to sharpen her "fine motor skills" and that is a similar benefit of model building.]
As long as it's fun, keep doing it.
