Many factors go into the pricing of a work of art. The most important aspect is whether it is an original work of art or a reproduction. In the case of sculpture a commission would cost more but there is only a single casting of the piece and it is designed in tandem between the patron and artist. In the case of a reproduction there is no original, instead a limited number of castings or prints that make up an edition.
It is up to the patron to decide what will best represent their goals for a work of art. There are many forms that a vision can take, some more literal and some more symbolic. Please feel free to contact me to assess how I might facilitate your vision in becoming a work of art.
