I Draw Moomins

My Polish friend told me about the Moomins. The Moomins are central characters in books and comic strip by Swedish-speaking Finnish writer and illustrator, Tove Jansson. You can read more about the Moomins in wikipedia and Moomin's website.
Today, I tried to draw four Moomins. 

This is the picture of Moomins that I got from the internet:

Front to back: Moominmamma, Moominpappa, Moomintroll, Snorkmaiden

And this is the result of my drawing:
