Re-reading this thread gave me food for thought:

Different folks see different things which, while not necessarily wrong, could have been done better.

I am wondering if what we notice are the aspects upon which we pay a lot of attention in our own work and if the things we didn't at first notice are things upon which we do not pay as much attention as we could in our own work?

'Tis worth thinking about when checking one's own work methinks.
