Hello. Thank you very much for liking the icon ^^. This link:
[link] is the base for the icons. Just pretty much color and design it however you wish in each frame then go to a .gif icon creator such as
[link] and you should be good. I believe you have to break up each frame into different images before putting it on a .gif creator but I believe this was how I did. It's been a year so I'm not to sure. Hope it helps.
