Stellium in Sagittarius (sun, moon, venus)
Mercury in Capricorn
Mars in Aquarius
Ascendant Geminis
I'll talk about these aspects because for me, they're the most personal in a chart.
General:
He can be religious, very independent, frontal, and sometimes sarcastic. He could have strong moral convictions or the opposite (the lack of them). He's intelligent, mental and eloquent. But sometimes he may have a problem to express clearly what he wants/feels.
Emotionally
He's really very independent, he don't make bonds so easily with people. He has a lot of emotional energy and strength (Moon sextil Mars); He has Moon quintile Uranus what makes him original, eccentric and detached.
In Love
He is indecisive, and he can promise, promise and do nothing. Is a gambler and he also could gamble with the hearts. Seeing love as a game.
He's intense and could have jealous issues (Pluto in the 5th house), he can also be very generous and understanding (Neptune), but once more he loves his freedom in romance and will not compromise so easily (Uranus).
His Pluto has some squares to personal planets so I can say that he's a control freak.
He has also more mutable aspects, which I would say that he's not constant and stable... but the opposite, he will always be in constant changing of ideas and feelings. Mutable fire... Impulsiveness.
The most strong characteristics: extremely independent and detached.
