Were supposed to have three zodiac signs. At the time we were born all the planets and constillations were in a particular place. We have a sun, a moon and an ascendant sign. They are the most important ones. The rest of the planets and stars also have a big part on your personality traits.
I would check out this website to get your personal portrait. All you need is the exact time, date and location of birth. Pretty cool been using it for years.
