Time is Like an Onion

This is another 12x12" acrylic done at school. I enjoy doing these little paintings at my desk. They make the days go by so much faster! I get the kids working and then pick up my brush. It is nice to have pretty good classes to work with instead of babysit. I have a couple of kids who need to be monitored, but most are busy doing their art. I used a glaze to separate the onion from the land and add a bit of shadow to the dinosaur egg. This is all about time being in layers like an onion...are we adding to the layers or peeling them away?
