Although it's very cute and nicely animated, it has way too many unique colors for such a simple colored piece. Of the visible palette that fits in 10 colors, you have 36, many of which are completely unnecessary. If you have problems with controlling the use of colors, it is good to make a palette in advance to which you subsequently add only the really necessary shades. But good work, nevertheless. 
Thank you for the advice! I really appriciate it
I have simplified it within a colors palette. It have 9 colors now and does look better!
