This turned out great. I am especially proud of her mane.
Now, you're probably wondering what this is, but I'll explain. Be warned, possible season finale spoilers ahead.
Apparently, once the Mane 6 unlock the magic box with their respective keys, it opens a Rainbow Kingdom and they get some new "Rainbow Power" magic and all look like this.
Alot of people over on dA are bashing the RP designs, but I think they're kinda cool.
The official designs are here: http://3.bp.blogspot.com/-iwvaNcbfFDM/Uv4xnrDIoGI/AAAAAAAAwq0/1f8EH9BmhxI/s1600/large.png
I think I'm the first to do this, I wonder if this will start a new fad.
