Baby girl name!!

Me and my husband are expecting our 2nd daughter!!! We’ve been discussing name ideas and decided we wanted to go for a longer name again (first daughter’s name is Marceline). My husband mentioned he really likes the name Valentine. But even tho this is a gender neutral name it just feels a little too masculine to me I guess? But I do absolutely love the variation “Valentina” or “Valenteen”. Out of the 3 variations which do you think would be better for a baby girl?
