I think duolingo can become a reference to you!
A simple and easy art to animate, you should check duolingo's yt channel and analyse it.

Thank you!
But i was looking more for an improvement idea for the character 🙏

add some lil tuffs of hair since your wanting to do a duck. the mask can have some grommets on it for adding detail

i think a cane would be a good idea too. play around with different types of canes
