I made a little gif recently and happened to hold on to some of my process work. So I thought I'd post that work here so it doesn't go to waste!
Here is the initial sketching phase:

If I wanted the final thing to look really nice, I would've made the sketch cleaner before moving on to the lineart. But I was just messing around, so it worked fine like this!
Lineart phase:

I added a few extra frames in this phase, mostly for hair movements/follow-through. I probably could've added even more to make it smoother, but I liked the pop-ish feel of the animation at this point and decided to leave it as it was.
Final GIF! (again):

Then I just had to add color! There's a way to shade animations as well, but I've never tried it before. Maybe I'll come back to this some day and experiment? Either way, it was a lot of fun to mess around with a short, low-pressure animation!
