I believe the first shift is after the first line and the second shift is after the eighth line. The first one goes from talking about something she isn't to something she is. The second it when it goes from describing he r to he actually speaking.
I believe the title is now talking about the new building of the Statue of Liberty. I believe the theme of the poem is about the new immigrants that come to America.
