In "Unfinished Masterpieces" by Anita Coleman, how does the narrator characterize Dora?

The speaker points out Dora’s ability as an artist and
sculptor, and William’s clear ability as a storyteller and raconteur. The implication of
“Unfinished Masterpieces” is that economic and racial conditions prevented both these
characters from developing their talents and therefore from making artistic
contributions equal to their native abilities. In fact, William boasts of never having
worked at anything for anyone. Both characters are hence “unfinished masterpieces”
because of the deprivation that both experienced. Both Dora and William may be seen as
symbols of blacks and also, more generally, of people who have been denied the rights
and opportunities to develop their skills and their humanity.
