(FN) [name]Emma[/name] (MN) [name]Karina[/name]
I think its beautiful, just wanting some different opinions on the name.
I like it but I have to admit that [name]Karina[/name] reminds me too much of [name]Katrina[/name] - as in Hurricane [name]Katrina[/name].
Beautiful 
I really like [name]Emma[/name] [name]Karina[/name]. It’s feminine without being frilly, and [name]Emma[/name] is such a classic but [name]Karina[/name] freshens it up a bit without being trendy or too modern. [name]Lovely[/name] choice.
It makes a perfect double name. If that’s not the way you’re planning on using it, I suggest you start considering it.
