I partially agree with @notadoc that it's basically not good, but also his criticisms could be fleshed out. As for faces, well, the very jean clottes mentioned in the article explored chauvet, and the lions there (http://thestorybehindthefaces.com/wp-content/uploads/2011/04/chauvetcave_lions_agostinoarts.jpg http://thestorybehindthefaces.com/wp-content/uploads/2011/04...) had such odd faces that clottes (or someone) speculated that they may have represented particular (edit: I meant specific) people. They're surely very odd for lions.
