What constellations are the people in One Piece?

I don't think the official answer is appropriate enough.

Luffy: Taurus → Sagittarius (liberal optimist)

Sauron: Scorpio → Absolute Scorpio

Nami: Cancer → Taurus (Miser)

Wu: Aries → Libra (indecisive)

Shan Zhi: Pisces → I agree.

Qiao Ba: Capricorn → Aquarius (Buddhist youth)

Robin: Aquarius → Capricorn (boring)

Frances: Pisces → Aries (passion)

Brooke: Aries → Cancer (Gentleman)

what do you think?
