This is an experimental painting, I applied oil pastel on opaque tracing paper.
The initial painting looks like this:
I realized that the smooth surface of the tracing paper is rejecting oil pastel from blending and layering, therefore with few strokes I finalized the painting. My intention is to make the daisy smile, good thing of tracing paper is, I manage to use tortillion to work out the daisy petals.
I think this is not so bad, I think tracing paper are suitable for oil pastel painting that does not rely on blending.
