I know this has many mistakes but I practice a lot

Please donīt be too harsh. I appreciate helpful and constructive critique though. Iīm really insecure about my animations, itīs so much more difficult than drawing and I hesitate a lot about submitting them. However, this is my first coloured one, and Iīm curious what you think.
It is

īs character Eliana, I wanted to do something for her because sheīs so awesome. She draws a lot for her friends just out of generosity and I got so many beautiful pictures from her I just had to thank her somehow

I wanted to animate Eliana doing something funny and easy to animate, but she turned out kind of bitchy and dislikable. xD Oh well.
Oh and her head got squeeezed when I transformed it into GIF :/ And itīs not as fluid as it is on my computer.
...
Iīm tired.
