The horror movie idea was a sillyness of mine (not completely bereft of sense, but it is only a particular and rare manifestation of Saturn and with Venus in Scorpio it didn't seemed so absurd).
Well often actors are seen as lively people like Jim Carrey/Eddie Murphy, but there are also actors that must interpret cool blooded politician etc, maybe I also hadn't gave enough importance to the Moon-Venus square since Venus rules both the Sun and Mercury.
Interesting that you mention music and writing, I tought about music, but I was uncertain, which music do you compose and what you write? With how much success?
I do not think that the Saturn-Moon conjunction is much important: it is separating and with nearly 4° of distance, more interesting are the Moon-Venus square and the Moon-Sun trine.
Still Saturn is an important influence for the Moon since disposes her.
I think that the Moon is influenced by making you more cold and with the need for organization and structure in your life.
Being lord 6th it could give you some propensity to illnesses, but being in domicile shouldn't be too terrible (well I am not an expert of medical astrology though).
It is also the lord 5th and aspecting the Sun and Venus, it could give you more structure and discipline in your approach to fun in general and also to creative and artistic endeavours. Saturn is also related to "logic humour" like sarcasm or irony (have you ever read the books of Ernst von Salomon? he had an eccellent irony and also he had an important Saturn influence).
Well with a quick analisys like this I do not know what else could be of particular relevance.
Maybe we had not worked enough on the fact that Mercury is in the 2nd house, you could work in a 2nd house related place, a bank (the 8th as other people's money would be more appropriate, still Mars lord 8th is in your 10th), a wardrobe, a food store, a storeroom (with the lord 3-9 trine you could also try import-export, goods delivery).
About Mercury every Virgo and Pisces rising generally have the lord of the ascendant and of the MC represented by the same planet; this is not a special feature.
It could suggest that you will be self-employed since Mercury is also without aspects (and also with the Moon in Saturn's domicile, and with an, although weak, conjunction and the Sun lord 12th of isolation is in the 1st house).
With Jupiter lord 7th in your 1st house if you do not succeed as an artist you could be a good seller.
