I do need to correct not having Derpy and Littlepip meet, but...!

From what I've seen, I liked how you portrayed Mami and I honestly hope that you pull Mami into someone brighter real soon. I've come to learn that characters who are pulled early are double-edged blades: on one hand, you have a lot of room to develop the characters, especially if you never liked how they were in their series. On the other hand, you miss out on some of the good developments. Mami's obviously one of those unique ones, though.
