Even though this episode would have been more fitting as a two-parter, I thought it was really enjoyable and heartwarming, and served as a decent enough finale in case the show ever got cancelled (though I'm glad it's getting a 4th season).
When I saw Pinkie like that I actually cried. I mean, with her hair down and her cutie mark changed that would mean she never broke out of the monotony of her old life and so was never happy and so never made any friends and so... By the way was I the only one who felt this episode was a bit rushed?
Your picture actually captures what I believe to be a secondary moral to the first half of the plot: Just because people think you should do something or you have a talent for it (Cutie Mark in this case) doesn't mean you'll be good at it. Or put another way, yes you can be anything you want to be. But will you be good at it or fulfilled? As this mixup shows, no; no you won't.
i feel the worst from applejack. thought everyone else is struggling she looks like the only one who's completely broken hearted. then again maybe i just can't bear seeing one of my favorite ponies cry.
How would they have worked the flying and racing in for her though? I think that's a problem that they ran into writing this, so instead of RD's "Major", they went with her "Minor", to use college degree terms.
I like how you caught Applejack's crying bit there. Also, the positioning of every pony in this picture is clever. Going counter-clockwise, Applejack's Cutie Mark is on Pinkie, Pinkie's on Fluttershy, Fluttershy's on Rainbow Dash, Rainbow Dash's on Rarity's, and Rarity's on Applejack's. Meanwhile, Twilight is dead in center, and she's supposed to be the pony who fixes everything.
This pic captures the spirit of the episode (the main point in my opinion). Amazing job!
