It's probably complex to say it just looking at my natal chart but if I got it well the most suitable jobs for me are artistic right ? Cause when I look at my Saturn in 5th house I can be a very good technician but no so good as an interpreter
Do you know from personal experience that you're a good technician but not such a good interpreter? Or are you just saying that because you see Saturn in your fifth house?
It's your personal experience that counts. Not what you think your birth chart says. Every assertion ever made about any placement in a birth chart is not universally true.
... also my Venus being retrograde AND in the 8th so I wonder if it has some big consequences on my artistic abilities ?? Cause I feel for sure that I don't always express outside what I feel within me or just in some contexts (even if I can feel things very strongly) !!
Retrograde planets do tend to show up very strongly on the internal plane and have trouble manifesting in the outside world. But that's not always a bad thing. Retrograde Venus can mean a lot of incubating, a lot of internal process, which eventually becomes a very creative, never before seen manifestation of your artistry.
And there are two things that will happen in your lifetime, when you're born during Venus retrograde: your progressed Venus will turn direct, and you will have a progressed Venus return.
To find out when your progressed Venus goes direct, look up the dates Venus was retrograde in the year you were born (you can do this in an ephemeris). However many days old you were when Venus turned direct, that's how many years old you will be (or were) when your progressed Venus turns direct.
The ephemeris also shows what degree of what sign each planet was at on any given day. However many days old you were when Venus got back to 23 Leo, that's how many years old you'll be when you have your progressed Venus return.
Since Venus rules your career sector, changes in its direction, and the progressed Venus return, will correlate with breakthroughs in career. Ben Kingsley, the actor best known for playing Gandhi in the movie
Gandhi, landed that role during his progressed Venus return. I, like you, have a retrograde Venus ruling my MC (and my fifth house), and I first took an interest in astrology when my Venus was turning direct by progression. Now I'm semi-pro.
As for Venus being in the eighth house, the eighth is considered a hidden house because it doesn't form a Ptolemaic aspect (sextile, square, trine, or opposition) to the ascendant. In traditional astrology, it's said that house doesn't see the AC. However, it does see the MC. Planets in the eighth support career and public reputation. And while your Venus is in the eighth house Placidus, it's in the ninth whole sign, so by that measure, it does see your AC. It's not as hidden as you might think.
Being in the eighth house Placidus might give it some extra edgy, creative quality, as would its square to Mars in Scorpio. Again, something you can use in your art.
At the end of the day, your Venus may not show up as Venusian in the sense we tend to think--flowers, sunshine, pretty in pink--but it's still artistic.
