Sting Production - Rough Animations

I have been working into animating the minor characters featured in the sting and their progress is as follows:

My animation of the smaller birds flying at the beginning of the sting. My team mate liked this and wants to mimic the same birds flying across the screen but going in the opposite direction.

I found it more difficult animating the ducks flying out of the trees as I really had to concentrate on the wing cycle. I feel I have made progress with the animation so far though. The ducks are escaping from a gun shot in the sting and I therefore had to adjust the timing accordingly, therefore making it a quick animation.

I created these quick sketches of the squirrel which I have proposed to my team mate to have run down the tree at the beginning of the sting. At the moment I am waiting for feedback to see if he likes the idea and I will then hopefully go on to animate it.

I gained inspiration for this character from the original Tex Avery video which features the same character:

I decided to have a go at trying to animate the basic shape and form of the squirrel myself and I am happy with the progress so far:
