Perfect loop ruined by slowly moving clouds. I usually edit it so the clouds stay still, but in this particular case editing the clouds and keeping the image’s quality at the same time is beyond my skillset.  
That’s one thing Twinkle Wish Adventure does a lot - slowly moving clouds. Subtle yet enriching.  
Also Cheerilee has surprisingly large number of poses in this scene. I expected her to switch between two or so poses, but no, she has whooping seven poses.
