Not sure, but I think this might be the Bay of Fires in Tasmania, that I have painted several paintings of before. My daughters went to Tasmania a couple of years ago and I asked them to take pictures so I could paint some beautiful scenes that I will never get to see. I played around with a palette knife on this one. I’m really liking the textures.
This is actually larger and not square, but my regular camera is not working very well, so I saved this from my Instagram. The actual painting is 12″ x 16″ oil on canvas.
