It's a very Thal face, in an archaic sense. The chin projection and smallish highish occipital diverge from that pattern.
The utter lack of backswept mass seems to constitute a subtype which has low impulse control/prioritization (in terms of values) but as a tradeoff seems to incur high artistic inclination/skill. Debussy and Sargent are my go to examples, although I recall stumbling across a third which now eludes my recollection. Also (independent of the above), he lacks frontal mass- that's a good example of a 45 degree angle slope (this is part of the archaic descriptor and contrasts with Amuds, which have greater frontal mass).
