"Overjoyed" Poses

Here are my poses for the sentence "Overjoyed"
In these 3 slides I wanted to show someone who won the lottery or something like that.
He first gets really surprised about what he sees, then he curls together to let out the scream/loud "yeah!" sound of his life, just before he jumps into the "success" cliche pose.

The only one I am not so sure about is the third and final picture. I keep comming back to the question "Is it powerfull enough?"

Thats it for now. Time to work some more on the "Ball with tail" project.

See you later!
