I looked up images of plankton for drawing and then I read about them. I learned that they are classified not by taxonomy (as so many other animals are), but by ecological niche! There are numerous types of plankton – both microscopic as well as macro.
I decided to use acrylic paint for the “luminescent” factor. I have much to learn about using this type of paint. I’m taking a Lisa Congdon class on watercolors/gauche through Creativebug.com (“The Daily Painting Challenge”). It was $10 for 30 mini lessons on pattern-making: a great deal!
Not sure where I’m going with this art, but I am enjoying the process.
