Nice. I think it works as a full feminine name.
I wouldn't have guessed that it has an international vibe, but I will certainly take your word for it.
Nice as a nickname too, although doesn't seem as natural to me as nicknames that use emphasized syllables.
Seems glamorous and gentle, maybe aloof.
Feels a little lightweight, like
Ella, as if it's missing a consonant - but I like it much more than
Ella.
I guess in the US, if it were a full name, there'd be many occasions where people needed to be taught that it's not AIR-a but AH-ra.
