If you're new to astrology I suggest first doing some research on natal chart interpretation. I don't believe anyone will do your complete interpretation for you for free because it would simply take too much time and it wouldn't do you any good. Also the questions you posed are pretty general so it's difficult to give you any valid answers.
True, your natal chart does tell you about your character but the variations are infinite. Nothing in astrology is set in stone.
I'd really recommend doing some reading of the basics.
Just google astrology and see what comes up. Learn about planets, houses, aspects and then start looking up parts of your own chart. For example: Taurus ascendant Venus in Libra
There are hundreds of descriptions on natal chart planetary positions (signs, aspects, houses) and after having gone through the basics by yourself you'll probably be able to ask more specific questions. We'll be here waiting
Just a comment on the grand water trine: From my personal experience I've found the people who have it, have really strong emotions and creative abilities but rarely expressing or using them. They seem to marinate in their sea of (mostly negative) emotion but not like self-pity, more like life's hard and they've come to terms with that. But that observation is made purely on 3 people I know and the rest of their charts strengthen that. It depends on the planets involved and the houses they occupy and the house rulers and .... (too much information/variation)
And also, what people here taught me: Always look at your chart as a whole. You find out what an aspect between planets could mean and you apply it to the whole, how it plays out in YOUR life. Many people can have that same aspect involving the same planets in same signs and houses even, but it can play out differently for them because of the whole picture.
I hope I helped some. Good luck on your new ventures.
You won't regret getting to know yourself
