This is actually one of my favourite moments from the series. A little detail that showed that while she might be a mean and spoiled brat, she's also just a little filly who thinks her dad is the best dad in the world.
That's really sweet. I'm a sucker for stories where the father and his kid have a really good relationship, and Diamond Tiara is definitely a Daddy's girl. They really need a story about Diamond Tiara and/or Silver Spoon without the CMC as the stars, or at least give more of a glimpse to their home lives. I also wouldn't say no to more Featherweight and Twist in plot lines. This scene reminds me that unfortunately Cheerilee really doesn't do much disciplining as a teacher. Fillies fall asleep and don't get scolded for disrespecting the guest speaker, Diamond Tiara can pass notes and make a blank flank comment and Cheerilee misses the opportunity to put her hoof down and say "Name calling is never appropriate. Foals, don't laugh." I want to like the teacher but in a way she contributes to plenty of classroom angst and it's ridiculous. Even her starring episode is fairly annoying. Rather than have a heart-to-heart talk with the girls about how she realizes they meant well but giving ponies love potions AFTER they outright state they don't mind being dateless is presumptuous at best, dangerous at worst she just decides "oh, Big Mac and I will wink and use more shoopy woopy adjectives, make the CMC think the spell isn't over that will really shock them, ha ha!" Real mature, Cheerilee. So I guess I even like that she's been reduced to being off-screen, like a Charlie Brown teacher or something. The textures in your pic are wonderful, and the expressions really sell the scene. I also like how the outlines are in different hues, just like on the show.
