Since cards are getting claimed quickly, I will briefly outlines some meanings behind each. Their names can be misleading.
My Disclaimer: The entire tarot system is set up vaguely on purpose to allow much room for individual interpretation. There is no correct meaning behind any of these cards. I am simply outlining one or more common interpretations for each from my sources. If the reader is using the narrative method (like in the movie The People Under the Stairs if I remember that scene correctly), these meanings do not even get used but instead the reader builds a story based upon the action and details in each illustration.
THE MAJOR ARCANA
These cards are unique to tarot because they belong to no specific suite. I will agree that they are the most iconic and fun, but in actual readings, the Minor Arcana are more useful. Major Arcana cards are broad in their meanings. Because I am very short on time, I will merely outline some brief meanings of each card and will not describe how they are traditionally illustrated. If you would like for you illustration to resemble the classical (which is in no way required nor even suggested), you can easily enough look it up online; it will be the first image when you google the term "tarot" and the name of the card.

This is one of those cards with a misleading meaning. It can mean actual lovers, but more often it signifies a commitment. That commitment could be a marriage, a partnership, a contract, or a promise.
This can mean forward movement. Other ways to describe the concept would be drive or staying on track. My primary source made the interesting choice of illustrating her Chariot as a train.
This means the type of strength that we could call grace under pressure. Related concepts/alternate interpretations include confidence, courage, poise, and self control.
This can mean either Independence or solitude depending on whether the character wants to be alone. Individualism is another likely interpretation.

It means just what it says, Justice. That could involve the courts, general fairness and objectivity, or truth.
There are two main ways to interpret this card. It can means suspension (as in not moving, a holding pattern), or it can mean a new perspective. As a character, the Hanged Man is often a traitor.
This is the most likely card to misinterpret. It usually simply means change, not literal death. Whereas the Magician is a more purposeful change forcing his will upon the world, the Death card is a more inevitable change like the circle of life.

A negative interpretation might be that a system is unstable or collapsing. A positive interpretation might be the removal of obstacles.
The can mean a wish. As a characteristic, it can indicate awe.
This can mean the unknown or hidden, like the dark side of the moon. Even moonlight is merely a reflection of something else.

This can mean destiny.
This can mean completion and wholeness, even fulfillment. The world is the final card in the Major Arcana and the end of a story.
