Alright for a beginner.
Your 'artwork' isn't exactly something to be desired, I liked your process of drawing, but I'd like to share a little tip with you to help you improve it.
If you draw the completed image to start off with, erase a little bit, create a new keyframe, erase some more, and then continue this process until you're back to a blank canvas, you can highlight every keyframe, and right click, then select "Reverse keyframes" for a smoother drawing effect.
If you didn't understand what I meant, check this out for a video tutorial about what I mean:
