These beautiful birds of  prey are all painted on various weights and different types of sourced leather.  My principal when painting on leather is that I would never depict an animal that is not a natural carnivore.  We are humbled by all the diversity and beauty of the natural world.  All the sizes given are for the actual image as they are all mounted on a white board  and framed appropriately for the artwork, which makes a good background and shows the image to the best advantage.
