The heroine of the "The immortals" books by Tamora Pierce actually -does- raise a dragon for a while and has a deep relationship with all animals - so my first thought was that this might be an illustration for the story. But also as a stand-alone picture it is very beautiful!
My intention was that the dragon is the child and the human the mother - she is using her falcon to try and teach her son to fly - but, of course, like all art, it is open to interpretation of the viewer :3
I love how all your paintings tell such interesting stories! This one is really heart warming; I could imagine this being a story from the world of "Howl's Moving Castle" or "Castle Waiting" It has that kind of sweet feeling to it
