A dinosaur/dragon laughing.
EDIT: Added bobbing animation.
Thanks for the suggestion!
I added a bobbing animation, now.
Doesn't look twisted to me. Unless you mean it isnt perfectly side on? which isn't a problem anyway.
Face seems kinda twisted, maybe you should focus on that more? Colours and shading seems fine.
Not bad, but why not animate the head/mouth as well? It could give more feel to it so it looks like it's actually laughing, because nobody laughs without moving their mouth/head
