I don't like it as much as
Lorena,
Laure or even
Lauren, but it's nicer than
Laurette and infinitely nicer than
Laura, so I'd place it as a pretty okay name in the scale of things. I think it's pretty frilly so it doesn't need to grandiose a middle name, but that said, I am fond of:
Lauretta Amandine - very pretty
Lauretta ClementineLauretta IoneLauretta Jane - surprisingly...
Lauretta Philomène
Lauretta Viviane - love!
