Nevertheless, concerning a pure artistic activity, a professional vocation, I am a bit upset by your Venus in its detriment in Virgo in the 12th house. I don’t know what to think about that. Ideally Venus would have to be stronger in sign and house, with more aspects, in particular from Luminaries.
That may be what a traditional astrologer would say, but from a modern astrology perspective, twelfth house placements are great for careers that put you in the spotlight--acting, singing, politics, etc. Many US presidents (at least, those whose birth times are known) have strong presence in the twelfth house... and, in at least two cases (Obama and Bush Jr.) an empty tenth house. Madonna has a packed twelfth house... and also an empty tenth.
Twelfth house reflects archetypes and the collective unconscious back at society. People with strong twelfth house placements have strong potential to become an archetype that people look to... like Obama's "change we can believe in" slogan, Bush's Marlboro Man image, or Madonna's becoming a 1980s icon.
In that light, Venus in the twelfth is very good for a career that requires you to tap into what the people want to hear, in a creative way. Comedy and acting are exactly that. Virgo gives it a groundedness that it might not have if it were in, say, Libra. Virgo may not be very good for the superficial expressions of Venus (shallowness, obsession with looks, uncommitted love, etc.), but it allows the deeper expressions of Venus to come through, often through some kind of work. Celebrity example: Charlize Theron has Venus in Virgo, and retrograde, too. Not only that, hers is also in the twelfth house, and doesn't aspect any luminaries, either... her sun and moon are both in Leo (and in the twelfth, too... so she also fits the packed twelfth house pattern!).
And then that twelfth house Virgo Venus trines Neptune and Uranus in the fifth house. It shares supportive energies with your desires to do what you love (fifth house), and Neptune shares the twelfth house's implications of tapping into underlying archetypes... and Uranus is all about being different, creative in an even more expansive way than Venus. Having them in Capricorn could give you great discipline and drive to pursue what you love, never giving up.
