On my Android phone --this is important because I am a GNU-Linux user-- I found this gifmaker app that allow you to make gifs. I do every frame on Sketchbook. I have tried dances
And I guess I become a better animator every week. I began from the bottom, very few frames, not much drawing, but my drawing is alright, so I like the results and I see the improvement from my first gifs.
