I uploaded a "Making Of" for my latest little animation on YouTube:
In case you are wondering what software I used, I basically used IbisPaintX for the whole thing (it has basic looping GIF animation capabilities) on my iPhone 14, I used the watercolor brush for coloring all on one layer, and I painted with my thumb+used HEAVY line smoothing features in IbisPaintX because I'm too cheap to even get a disposal stylus for drawing on my phone.
