This is an acrylic painting I did several years ago. The impetus for this was a class I took on abstract painting. As I am on the autistic spectrum, it is natural for me to be literal and detailed, and to paint almost photorealism. In one way this is fine, but I would like to go beyond just a technical, literal rendering. So, I’m going down the abstract path for a while. I find it very freeing. I don’t have to worry about making something look realistic.
In this piece, I went very organic. I used natural earth colors, including a lot of burnt sienna. I first applied acrylic modeling paste to a canvas panel, and let this dry. Then I painted it. After it dried, I sanded down the tops of the ribs, and exposed the white underneath. The idea here is a an ancient natural artifact or fossil that has been exposed by erosion.
