Just got to looking at your chart.
I was reading the four page on this site:

And I was thinking, hmmm, this sounds Saturnian as well, though a different flavour.
Your Saturn is Aquarian, and strong (in domicile, strongly approaching the dsc, and Saturn is traditionally associated with the eighth house (I read whole signs))
So you might want to assert and maintain your individuality and maintain some aloofness (Saturn in Aquarius):
By whole signs, assuming your birth time is good (and I will), then you've Mars in the first, which would to me suggest assertion of self identity:
And then there's the Moon and Venus square with Saturn:
It all makes sense to me.
I apologise if you weren't looking for an analysis, I almost can't help myself.
This is pretty cool though, and I'm already thinking about using Enneagram testing in conjunction with astrology.
