You will often see the Moon card mentioned in relation to creativity and creative energy and by extension, the arts in general. This is because this card is mood-related, connected with things that are felt inside and deeply rather than necessarily tangible. Creative flow, self-expression of all kinds via the arts and culture, as well as the feelings that they invoke in others, would be represented by the Moon card.
Because of its association with tangible beauty and prettiness, the Bouquet card can be used to represent the visual arts specifically. So painting, drawing, and design, makeup artistry, even fashion, anything where “the look” is the key can be represented by the Bouquet card. Bear in mind this is about “on the surface” rather than the more in-depth creativity and feelings invoked by the Moon, which is more about the arts and creative urges and feelings in general.
