The pink base is one of the Jade holographic polishes and it's gorgeous. The rest of the art (minus the brown pants and brown plant pot) were done with acrylic paints. The pinkish-orangish line on the man's face is supposed to be his beard, not his mouth, but my paintbrushes are awful, so it was challenging to paint.
My husband was in a school play of Little Shop of Horrors, but I've honestly never seen more than a few minutes of the movie. Have you seen it?
