You could always try Ava Joy, too. LOL! Not that I am biased towards the name...
Anyway, it seems a one or two syllable name would sound best with Ava.
Ava Michelle
Ava Nevaeh
Ava Grace like all are saying (pretty)
I like
Ava Marie and
Ava Rain
Renee is my middle name! LOL!
Depends on how it all flows with your last name.
Ava Grace is really pretty! I love the name Ava, too.
Hey looks like we were thinking alike at the same time! haha
