"I'm never going back, the past is in the past!" is clearly a lyric stolen from Frozen's "Let it Go".

2. "...singing a beautiful song of her resolution and becoming one with the wind and sky" is also a reference to Frozen's "Let it Go" as Elsa did the exact same thing in the movie.

3. "She completely redeems herself as a new pony... nopony will see her cry again!" This is also a ripoff of Frozen.

4. He clearly used a base for this picture, as we can see a few splotches of uneven lines here and there. The mane and tail is a little bit sketchy as well.



So clearly, this is a fake screenshot!
