My next step was printing the mustard seed plants. I wasn't sure of the base color I wanted to use so I did some test prints (I made a practice piece to try my ideas as I went through the process). The gold is printed over a brown base and slightly offset to create a shadow effect.
The next two pictures show the brown base print and the gold over print.
Additional prints are added.
The last step with the mustard plant was adding an additional print layer on the flower portion of the plant.
