Raevyn is a little much. I would just spell it Raven. While Raevyn is cute for a baby, it wouldn’t be so cute for an adult.

Being a Raven myself and already having people misspell my name (Ravin, Rayven) I can assure you that No one is going to spell it correctly the way you've chosen. If you like the name, maybe just spell it normally? It's unique enough without the complicated spelling. I've never met another Raven in my 23 years and I've liked in 3 different states and 5 different cities.
