Minion - Work in progress

Have you seen the movie "Despicable me"? A computer-animated comedy film about a super villain who adopts three little girls who bring out the good side of him. I didn't know it until I visited my sister who watched the DVD with me. Actually the title and movie poster did not appeal to me at all. But the side characters, the minions, are very funny and adorable. And after watching the whole movie and all the extra features on the DVD I started to like them too. There are more mini film clips of the minions on YouTube and next year there will be a whole movie featuring the minions.

My sister and I then searched the web and found a pattern for a crocheted minion. Hurrah! Stephanie from "All about ami", the very talented amigurumi and crochet artist, wrote a pattern for a minion. As my sister loved it very much I promised to crochet one for her. So this is the start of a new amigurumi project.
I bought some yellow, blue, black and grey yarn and started to crochet the body. I just did on third of it and I am curious how it will turn out. What you see in the picture below is the upper part of the head
