Talaria, I find these charts hard to read. See if the free charts at Astrodienst
www.astro.com are easier to interpret. I take it that the first chart is your natal chart. What is the second one?
The house system you use can make a difference if planets are close to a house cusp. You might play around with a few and see which one seems like the best match for you.
In an unequal or quadrant house method like Placidus, you would have Aries on the cusp of your 4th house, with a very strong Mars in its own sign of Aries in the 4th. This would give your home life a more combative edge than a peace-loving Venus in Taurus would suggest. Despite your inherently adaptive go-with-the-flow Pisces nature, this Mars gives you a strong feisty streak!
Venus in Taurus might give you a good artistic sense, a sense of good taste, and even some singing talent. However, it is opposed by two planetary heavies: Saturn and Pluto. Venus might have been suppressed by senior authority figures and bullies; especially given your mutable and 12th house placements. But Venus is "at home" in her own sign of Taurus. Whatever seems good and true and beautiful to you: trust your instincts on them.
Astrology does require us to master hundreds of data bytes. This can seem overwhelming. I recommend you pick up some good books and websites on natal chart interpretation, and just be prepared to be a novice for several years, while the data bits and pieces take their time to sink in.
A bit of astrological technique that I find very helpful is to look at house cusp rulers ("lords".) As in, with Aries on your 4th house cusp, Mars by its own house and aspect will have a lot to say about your 4th house matters.
Although each planet, sign, and house has dozens of meanings, in terms of a natal chart reading, perhaps it is easiest just to memorize the core meanings.
Sun: sense of self, your core identity
Moon: needs, emotional nature, Mom, home
Mercury: mental nature
Venus: what you attract, what you find attractive. rules the arts
Mars: your innate assertiveness and aggression. rules athletes
Jupiter: the principle of expansion and optimism
Saturn: the principle of restriction and fear, but it responds well to patience, reality-checks, and hard work
Uranus: sudden change
Neptune: illusion or disillusionment
Pluto: rthless, inevitable change, but also the power for positive transformation
Houses: domains of life. These are not the same as signs, although some modern astrologers confuse them.
Signs: Here it is best to think of the 4 elements (earth=practical, material; air=ideas; fire=enthusiasm, action; water=emotional) and whether the sign is cardinal (initiative), fixed (stay-the-course) or mutable (adaptable, changeable.) So Taurus as a fixed earth sign is inherently material in its outlook on life, but also has fixity of purpose. Gemini likes the world of ideas, and is very nimble in its approach to them.
Then each sign has its own ruler (Mars=Aries, Taurus=Venus, Gemini=Mercury, &c)
Yes, each sign has its own personality quirks, but these typically follow from the basic building blocks of the signs.
Once you've sort of figured these out, then look at how the planets operate. Think of them like family members in a discussion. Some don't get along and even actively oppose one another's interests. Some are great pals. Others feel a lot of friction or tension together. Nobody is a unified entity: people are inherently messy and contradictory. We often feel conflicts between different parts of ourselves. Astrology shows this.
Confusion when you are just learning astrology is normal.
