Beautiful beautiful beautiful!!!
Okay, first off, I love how the animation is fully detailed by the way he is moving like he would do in the movie.
Second off, you got the colors perfect! This is what Sandy would look like doing this for real d's.
And third, I like how you made the rest of his face move along with his cheeks being squished in little circles. It makes the detail perfectly balanced.
Anyway, I am in love with this since I am a huge Sandy fan, SO TO ME, THIS WOULD MAKES ALL THE SANDY FANGIRLS SQUEEEEEEEEEE!!!!
Good Job! Wait, make it great, no, SUPER!!!
SUPER-DEE-DUPER JOB ON THIS FLASH ANIMATION!!!
