Negative or Positive masks
The other side of the coin.. to use another cliché.
The negative masked shape was done in white ink on a coloured background, so it has the same tonal values as the alternative positive masked one. However, this time the contrast of material and non-material is reversed. The white image is assertive and pushes the colour of the paper into the background.
This has the effect of making it a more dynamic image than the positive masked one. Whereas the first is put upon and suffering, this one seems to have energy-it could even be interpreted as a dancer. So, I reinforced this interpretation by backdrawing a spiral going up the body.
