Thanks for sharing your chart!
Ascendant is in Leo, so your Cancer Sun is your chart ruler. The Sun is also conjunct the ascendant. Strong position. This can create a highly visible personality. Bright. The Sun being in Cancer is disposed by the Moon, which is in Libra. You are likely emotionally sensitive and nurturing, while also capable of taking the lead. You probably care about fairness and social cohesion and naturally move to repair disconnection in your social arena.
Saturn and Jupiter in the 10th. These are both planets that often indicate major circumstances that affect your life. Saturn brings areas of limitation, restructure, and restriction, while Jupiter brings areas of expansion and opportunity. Often these planets create situations that affect large groups.
I take this to mean your public life (likely your career) will be involved in managing large-scale public troubles. In Taurus, it’s likely to be environmental issues, something to do with the earth, or perhaps handing basic and necessary social systems, like food, money, housing, land. You could end up managing these resources. Since your MC is in Aries, you might be taking some initiative or leadership role in this. Life is pushing you in some particular direction with these two planets here.
There is some tension between Jupiter and the Sun, with a square. A pull to expand that could threaten your health or mental health at times. Your body is probably a bit sensitive, and you need to remain grounded but still be in tune with your emotional side.
The Mercury’s square to Saturn indicate some level of struggle to stay mentally coherent—you could find that you need to push or restrict yourself some to stay at your best in communication.
With the Moon and Part of fortune near the IC, I’m guessing you are close with a mother figure. You could be the type to call home often.
The Grand Cross I am not as familiar with. I see that one of the planets involved is Neptune, which is not considered a major player in traditional Hellenistic astrology. But I’ll give it a go.
So it’s Sun—Neptune, Jupiter—Mars. These guys are all at tense angles to each other. You could think of the planets in opposition as being pulled forward by the planets they are in square with, like they are being levered forward. I think this is an intense pattern but with great potential for growth. You could find yourself in intense and overwhelming circumstances often, but when you overcome it, you get much stronger.
I’d consider Neptune the weakest planet in the lever, perhaps causing more problems than it can resolve. Neptune is about your ideals. Out of all these planets, Mars is the most empowered in its own sign of Scorpio. You have a grounded and strong drive to make things happen.
Your chart is pretty interesting, and of course there’s much more to think about. But that’s all I have time for! Best wishes.
