In a basic definition, negative space is space that is between objects or space that is left blank, positive space is space that is occupied or marked. This piece utilizes positive and negative space very well, and it makes the piece very interesting. It transforms both types space into representational shapes of actual things (fish/birds).

I really like this piece because it uses negative space (as far as space that is not occupied by form) extremely well. The shape of the black telephone poles pushing into the vast negative space occupied by the sky make the piece very visually appealing.
