The Queen of Pentacles represents a practical, down to earth, person, who's focused on everyday matters, financial stability and material security. The Queen of Pentacles often represents a person of earth sign/ascendant (Virgo, Capricorn, Taurus). The Two of Pentacles is a card of change and is trying to achieve balance during or after a phase of transition or a temporary situation. The combination of the Queen of Pentacles and the Two of Pentacles is about keeping balance and stability.
The elements of the two cards are Earth (Queen of Pentacles) and Earth (Two of Pentacles), which means that the situation they represent will move slowly but steadily. Too much earth could test our patience due to slowness or we may have the feeling that a situation is not progressing at all. However, that's rarely the case - change does happen, but sometimes it's too slow for us to notice. Earth cards generate too much "gravity", that's why they often cause feelings of impatience and even frustration, which if not controlled, could result in impulse action and decisions made in a rush.
