Here in Europe we call "Humanities" what you may address as "Liberal Arts". Therefore yes, "humanist" is fine, but uncommon, especially in the US. I'd say it's the kind of word a... Humanist would use, since it's the more philologically correct. Interesting to note that here in Italy the thing is reversed. While "umanismo" and "umanista" are broadly used, "arti liberali" is less common, while still correct.
