I like [name]Raina[/name] (much prefer the [name]Reina[/name] spelling though) and I think that [name]Raina[/name] [name]Camille[/name] sounds pretty perfect.
My favorite is [name]Raina[/name] [name]Camille[/name]! [name]Willow[/name] and Maylea seem sort of out of place to me and [name]Seraphina[/name] repeats a lot of the same letters/sounds as [name]Raina[/name] so that that flow doesn’t seem to work as well.
