I like very much the dark shadowy feel - very baroque and the fact that the faces are generally in shadow which is characteristic of 17th century sacred art (as we saw in Van Dyck recently) but different from the way that portraits are painted. This helps it to avoid the sentimentality that infects so many modern works of sacred art in the naturalistic style. I don't know many artists around today who are able to produce sacred art to this level.
