Just my opinions, and your mileage may vary:
Gloria Thomas:
Absalom and David as a prefiguring of Christ's sacrifice.
the Blessed Virgin Mary
This is good work. Her vision is unique, but I have the feeling that she is still searching for her own style - there are echoes of numerous artists here.
Kirk St. Maur:
Father Marquette. What is it about these people and draperies?
Frederick Hart (who apparently died in 1999):
from the National Cathedral
He's really uneven. Some of his stuff is great, some of it is just kitsch (especially the floating ladies). He has of the sculptors the best ability to handle his material though.
