I would say yes. But as I preach, if you read any of my over 100 teaching astrology articles, astrology is more complicated than that. All of your planets are in a zodiac sign and one of twelve houses which have multiple meanings. The distance and aspects each planet makes to each other is the most important thing in a horoscope. So I don't always know what to do with these questions.
I have written complete articles on all four of the issues you raise here, and I would appreciate it if people would read them before asking questions I have already answered numerous times. I charge $100.00 for a horoscope, and it isn't computerized, it takes over 10 hours of my time.
A Pisces Sun and Scorpio Sun pair is compatible, as both of you are water signs. The Scorpio will be dominant, but also loyal and sensitive if he really does care. He can read you like a book. Both of you are intuitive and creative. You need to be careful not to be a doormat to him, as Pisces women can be so adaptable they remake themselves to be what a man wants them to be. But you are very spiritual, Pisces rules the feet, so this last zodiac sign is where your spirit touches the earth. Also, Taurus is ruled by Venus, so it's an emotionally gentle moon, making you yearn for a secure partnership. You are a true romantic.
His Gemini moon means if you have problems, he probably wants to discuss them and make changes. It's good for communication. Moons next to each other in sign are generally fine. His emotions change, and Gemini moon people can tell little lies now and then, so watch for that. But in general, I think you two can go far if you want to.
I get these questions on a separate page from my article, where everyone can read my answers. So please don't be offended by what I said in the beginning. Too many people are wasting my time with questions which are answered in the articles and don't bother to read them. This message is meant for everyone.
