WOW, this is lovely! The swirling magic energy is a nice detail, and those expressions on an increasingly adorable Fluttershy face are absolutely priceless! I especially like the last two frames where those pegasus wings tear free from his her shirt as the magic tugs her down onto all four hooves. After having just recently drawn a Fluttershy tftg myself, it was such a wonderful surprise to see this amazing sequence today, and I salute you for creating it (and helping to keep ponies on my mind) :)

He has became best girl.

I just realized she has teats in one of the tf sequence

This is perfection

fantastically done
