I have qualms with some of the clueing:
24a: While SET OFF is perfectly fine to clue START, I don't see how START OFF means SET
32a: ONE KILLED bugs me as the def of a killer
33a:
Hispaniola sailor is pretty obscure
13d: Using Levi as an eponym for Italian bugs me
18d: I think that decoding the word should still result in a clue that parses. ELANCE is only a verb so 'half of elance' is nonsensical.
