I like it.
Fidelia used to be one of my real faves, but I lost interest for a few reasons. It reminds me of
Fidel Castro and Vidalia (onions), and I don't really think either of those is something I want. Also, I can't really pronounce it in a way that is completely natural to me and that I also like. With a delicate Spanish accent it sounds great, but that's not how American Midwesterners speak, for the most part - the nice Feee will be Feh, -lia will be -lee-uh, etc.
That said, I think it's pretty and sophisticated and classic and lilting and cheerful without being excessively fairy-princess whimsical.

That's all I got.
