Lerning to animate takes some time. I think this kind of motion really needs at least 3 frames to read well unless you actually draw in so motion with 2 frames.
Your biggest problem here, I think, is your colors. The light green lines really look bad. Where you trying to make some highlights? Also, you have 2 greens that hardly change at all so its a wasted color.
Thanks for your advice Im gonna change the Highlight.
Im not really good Im just begins , but I really enjoy that
