A little while ago, we posted a composition from a fan named Einar who is exploring the fates of the mane six when they had mixed-up cutie marks.
Now Einar is back with more pieces of his project. The first one is based on Evil Enchantress, and you can check out the midi and sheet music. Then there's a piece based on A True, True Friend which will follow after the Fluttershy piece we posted before. Again, there's sheet music and a midi.
Thanks for sharing more of your work, Einar!
