These sketches are homework for my painting class. The requirement is "studies for the exactly the same subject in different techniques." Since I missed the first three weeks of the semester, I didn't know exactly what techniques were supposed to be used. Acrylic was the required medium for the course but mainly it was opaque. I tried to either mix colors on the palette before applying to the paper or apply colors without mixing first. I also tried to use acrylic like watercolor or with ink wash. One of them was made in oil pastel, just an experiment.
