Here you can see animations for screens where the user may have a negative experience: a need to wait or an unsuccessful result. In these animations I try to amuse the user, evoke a pleasant emotion and make user experience more pleasant.
Below there is a series of animations dedicated to different holidays. Here my goal was to remind the user in advance that a gifts can be purchased in our application.
I did these animations in Adobe After Effects. Then I exported them to the Lottie.Json format to embed them in applications later.
