I've decided to share the GIF versions of my contest entries last year, one topic at a time! I hope you like them :) Hana was the first entry I drew.

I did the animation manually in medibang paint, using a group of layers and transforming them, bit by bit. Then, I exporting them one by one and adding them to the online gif service, ezgif. This was when I didn't know about AnimeEffects by Hidefuku and FFMPEG.
This marks the end of my technical rant. I wonder if anyone's interested in a visualized tutorial? I'll see what I can do if this gains some traction.

Hope you have a nice day!
