That river in Egypt

"This painting was done by Aleksandra Waliszewska. I don't know when it was made, or what the title is. There's not a lot of information about her out there, not much information about her artworks either. She lives in Poland, and was born in 1976. Her artworks are often very strange, but she paints cats quite a lot. She has many of her artworks on her instagram. I don't know what this painting is about at all, but if I had to guess then I would say that the light bird is the soul of the dead bird, since they look similar"
