It's very pretty.
My POV on names usually defaults to "what would I think of it on a newborn child of Americans who are a lot like myself" ... because I don't really have any other POV ... In that case I think it would stand out to me as a bit Old-Worldish, about like
Valeria or
Valentina or
Aurelia. Americans reaching for something that seems new/fresh to us, but isn't modern. It seems appealing as such, though, and just for the sound of it.
I like it a lot more than
Rosalie.
It seems more fashionable and "young" than
Rosa.
I like that it could have nn
Rosie or
Lia.
It's not a favorite of mine, not quite my style.
