Ciao Luxr !
My first remark, is that your natal chart also has a Pluto-Mars opposition, which your son has inherited from you!
second, upon checking your boy's natal chart, here is what I LIKE: his Country = Homeland & Family will be very important to him, both professionally, and personally:
Sun, Mercury, Mars in Cancer = Loves the home, also a Patriot.
Also: quick thinker, stubborn, but very smart. Fast thought, fast movement, very energetic. Slim, slender, athletic. In my opinion he could select a career to support his country, like a Policeman, or Military career.
He has Moon conjunct Jupiter, and these are not negatively afflicted by Pluto or other planets. He is EXTREMELY connected to you = mother, and your bonding will have a life-long duration. He will always be close to you, even when he gets married.
Finally, Pluto in the 4th house is not bad. I have the same placement, and it means that he will be TORN between his love for the family, and his need to succeed in his career. In my case, I am taking care of my elderly mother, but also several family members that need my support.
Not bad though, as this dedication is what he will choose.
Good luck!
