This still isn't to my specifications, but there is limited artwork of Fluttershy's rainbow power form, I'll likely draw more myself later and update the pack with my own art of her. But for now this is unfortunately the best I can do.

Tags I used when making this are as follows

my little pony, Harmony-Fluttershy, full body, rainbow power, Fluttershy, face shot

Hope to make this one better myself later on.
