I am doing a project in my painting class based on turtles as spirit guides in my dreams and their relationship to me as a person. Animal spirit guides were a belief of the Native Americans and turtles specifically were revered for their wisdom and power of fertility and growth. This turtle focuses on the aspect of fertility and growth. I wanted it to look as if its shell supported other life (the trees and flowers). It is hard to see from this image specifically but there are little embryos embedded in the smaller plates on its shell. The little people near the trees on its back are supposed to be me and I was trying out different places I could myself in the painting. Some of the details are a bit rough since this is a preliminary drawing for the painting itself. Any ideas for a backgroud color?
