EDIT 2019: Just found an old notebook with an accompanying poem for this picture in:2017:"Luna, no!"Celestia and Luna's great battle, just before Luna transforms and Celestia is gathering energy to blast her into the moon.I actually won the art contest at Ponycon UK 2017 with this painting! Awesome to have won.Elements are not by me, I got them here: techrainbow.deviantart.com/art…
