I know of several wallers who have announced they wish be known to all as the best.

It helps to have encouragement too, not just criticism.
However when you're building with odd shaped random material (rather than simple blocky easily shaped ones) it can sometimes seem to others like you have not done your best
Below are details from three different stone walls (where random shaped stones have had to be used) which are built by people who are considered by some to be among the best.
(The colour has been removed from the samples so that the stone is less recognizable)
