Mars opposite Neptune aspects can be problematic, but when they are applied to spiritual quests or creativity, the results are spectacular.
This is what Frida Kahlo emerged with after she read Freud’s Moses & Monotheism.
She was Sun-Neptune in Cancer opposite Mars-Uranus in Capricorn and Leo Rising. Her Moon was exalted in Taurus and conjunct the Midheaven. For extra volcanic intensity and depth awareness, she was also a Venus-Pluto person.
It is the perfect astrological signature for a grand-scale visionary artist. And the Moon-Midheaven often suggests a person whose work endures after their lifetime.
