It's very pretty but also a bit generic because
Sara,
Sarah,
Lara,
Tara,
Kara,
Clara etc. are all more common.
I think I would spell it
Yara.
Iara is prettier but in real life it could cause problems. I think people might mistake it for
Lara very often especially in some handwriting or they will think it was
Lara accidentally written in lower case.
