I've also started to experiment with acrylics again. I've been away from them for a while - and when I was working with them before, it was with airbrush. In this project, I am trying for depth and brilliant color using regular acrylics, the newer iridescent acrylics and believe it or not, glitter. Oh, and many layers of clear gloss medium. I have plans on doing at least a few of these.
It's difficult to see the glitter in a photograph, but you can see it in the dark areas of the top right.
