I sincerely hope you won't get this wrong- to me, it looks like a tree spirit, as when I first saw the picture, the corals reminded me of leaves.I don't know if you have ever seen Princess Mononoke, a relatively famous anime film. In it, there are little tree spirits (that look nothing like turtles, by the way) called Kodama. If the forest is happy, they are. I know, this is another comment that makes little or no sense to anyone but me, but in my own, weird way I'm trying to say that your painting is really, really beautiful. It makes me feel serene and happy.
lisbonlioness, I had to look up Prices Mononoke, amazing images, I have to be honest when a couple of people on folksy said they liked the leaves I was a bit taken aback as I thought how could a turtle be amongst leaves? but having just read you comment and looked at the amnime images I am quite taken with the idea of tree spirits, and I love you comment about the painting making you feel serene, that is so beautiful and made my day x
