Ancient Royal family

(I may actually do some clean lineart, shading, and a background on this but it is unlikely. I just wanted to do some art of Altalune when she was still a unicorn, less powerful so no galaxy mane, and with both her parents together(Also this Au Sombra is how he looked before going mad with power, maybe a year after this image takes place. This family is very tragic indeed. You are free to ask me questions about any of them, of course.)
