let's see. you have sun and venus both in the 12th house.
with venus and mercury both in gemini and both conjunct your
gemini AC.
this would probably make you very flirtatious and at the same time
you will probably be viewed as very charming and probably have
some physical beauty due to the venus ascendant conjunction.
venus and sun being in the 12th house poses some problems
especially due to the fact that you have a scorpio moon opposing mars.
those aspects seem to indicate that you would have a very deep,
passionate, and maybe lustful nature underneath your very glib,
chatty, and charming facade. you may have secret love affairs or
entertain secret and or dark fantasies.
your true personality is also hidden beneath the surface in the 12th
house thanks to your sun being there.
with pluto and saturn in the 4th house your family will be very important
to you and you may have problems of deep insecurities and issues
with your self esteem or confidence, however pluto is mostly well aspected which means that it may only indicate that you will have a very deep nature and you are constantly looking inward into yourself for inner transformation on a psychological and spiritual level. on the other hand saturn does
trine the 12th house planets of moon and venus and so it may not be
as bad as it sounds.
with sun in the 12th however you most likely will have a very private
and secretive nature whose depth only you know and people would never
guess from seeing your charming outside appearance.
you have a neptune singleton which gives you a more intuitive and emotional nature, the neptune is somewhat afflicted as it makes squares to saturn and jupiter and oppositions with mercury.
you probably have a powerful imagination, one that often frightens you due to the neptune saturn square, in fact you may have some phobias. you may be a dreamer and have a whole inner world to yourself, in fact there are some indications that you could be very artistic and creative, with neptune singleton and strong 12th house placements and moon in the 5th house in scorpio, you may have a very intuitive and artistic nature. neptune opposition mercury is very good for musicians so perhaps you write music, if not you probably can.
it seems you have a lot of depth in your nature, maybe it can be said a lot of darkness as well but at the same time there is a lot to be optimistic about, even your 4th house with pluto and saturn in it, it also has jupiter which will raise your spirits, not to mention saturn is exalted in libra and thus not as afflicted as it may sound. it will still bring some restrictions in terms of family and your inner world but it may harmonize and balance things out as well.
scorpio moon opposition taurus mars will probably cause alot of fights with people. either you are often antagonistic towards others because of things they did or said to you, or you feel they are doing so to you and you become quickly vindictive. you may have quite a fiery temper when the fuse runs out so to speak. this is in conjunction with your 7th house uranus oppositioning your venus. this will bring difficulties in relationships because your partner may often be confused by you due to either your demanding ways or your swinging passions. you probably are not good at compromising with people or in relationships, the stubborn energy of uranus oppositiong your venus, with a fixed scorpio moon oppositioning your fixed taurus mars gives you a very dominant and stubborn streak when it comes to others.
let me know how much if any of this made sense for you and if you have any further questions.
