First impressions: Your Sagittarius-Pisces luminaries fit her Gemini-Gemini luminaries really well, with your Moon tightly square her Sun-Moon. This is a solid interlocking of luminaries - a sense of being at home with each other and strong chemical attraction.
Also, your Venus is (widely) on her IC. You really, really like her! This one is probably hitting you really hard (or will eventually).
More complicated: Your Sun dies in closely to her Jupiter, moderately to her Mars, and a little more widely with her Saturn. Jupiter has the lead - mutual respect. Sun-Mars can be functionally physical though it's real characteristic is shoulder-to-shoulder teammates. Sun-Saturn is often troublesome - real the standard interpretation- but it's disrespect elements are likely outweighed by the respect-oriented Sun-Jupiter. (This theme could go back and forth over time. Her Saturn also squares your Ascendant.)
'Or course, the fact that your Moon aspects her Sun-Moon means that your Mercury, Jupiter, and Neptune also do this. Most importantly, this means that the close Sun-Jupiter goes both directions, which is quite good for a mutually respectful, mutually advantageous connection. I suggest you read the standard interpretations of Mercury to Sun-Moon, Jupiter to Sun-Moon, and Neptune to Sun-Moon:
