cool

The last frames don’t at the same position and it makes the picture as if it shaking.
Anyway, good work.

Thanks. I'm aware of that. I posted the reason below in DragonsLover comment.

I read it. Thank you.

Such a lovely dragon

Ohh, how adorable!

Nice! And like Atlamedes mentioned, one of the frames is moved a bit slightly from a few pixels, making it like it is slightly shaking.

That was intentional! FA seems to have issues when it comes to uploading thumbnails for animated gifs. Something to do with what happens if the last two frames are too identical (and as a result, produces a distorted-looking thumbnail of the gif that cannot be changed no matter what you do). So I shifted the final frame a little to prevent that distortion from happening. It's a quick solution for now until I find a better way to bypass that issue.

I remember of a post saying that the problem comes from the colour palette that is not indexed and must need to be to fix the issue. But yeah, I know that the last frame is used for the thumbnail.
