Is this snowboard right for me?

I just bought a new snowboard finally. Its a K2 raygun, size 164. Im a girl and i weigh about 150, its also a guys bored i believe because its definitely wider than my last one. The board is all terrain and thats exactly how i ride, i do a little of everything. But now i worry its to big for me, Im around 6 feet tall as well, so it comes up to my chin, id love your feedback if you think its right for me or not.
