Here are two paintings by the students in my class, "Beyond the Palette: Experimental Techniques in Acrylic." The assignment was to incorporate a number of the textural techniques we practiced in class into a painting of fish/an underwater scene. The top image is by Ed Hardy, and the bottom image is by Margaret Primack.
Don't these rock?! This class has gone so well that I've decided to offer a one-day workshop on the subject as well.
