Conventional western astrology doesn't work much with constellations, especially those located away from the ecliptic. Signs, Aries through Pisces, have names similar to constellations, but (in the Tropical Zodiac) are actually 30 degree segments of sky measured along the ecliptic from the Vernal Equinox point. Your torso markings may be coincidental or due to something other than astrology, IMHO. Dave.
It probably has a Greek myth attached that may hold some meaning for you. Many of the constellations do.
Also, the big dipper is actually supposed to be a bear, so perhaps that animals is special for you.
