I'm a male Taurus/Rooster and she is a Libra/Snake

She was born in 1989 and me in 1957. I have customers in my store who are this big of age gap and are very happy in love. I'm not so concerned about the age difference as I am curious about our sign compatibility. I was with a Libra/Snake for 11 years and she is still like my best friend. Any insights on this combo-match would be wonderful. I know the Rooster and Snake are a good one.
Thank you!
