In response to this, I gifted her with her own requested picture. She suggested I make something for her OC, Harmony, who essentially is the Tree of Harmony in pony form. You can check out the picture I made for her here: http://fav.me/d7ms1p9
Drawn by Heilos
Colored by Sorelstrasz

Unlike on Deviant Art, I am perfectly fine with uploading the full resolution of the picture I have, so enjoy the high res :D
