One problem we all have to overcome is macro vision, when we look at tiny details up close, that to a person viewing from arms length or further will never see or notice, but we know that something is not just perfectly correct and fuss over it.
Sometimes at small scale, you just need to get it close enough to be seen, but not as good as a large scale model which you can see things more clearly.
As on old photographer, we had this when folks would hold a print at their nose and inspect a large print which would normally be viewed at 3-5 foot distance, and they complain how grainy the print was.
