I began by doing some rough poses and sketches in Photoshop to familiarize myself with the characters.
|I used this reference image in order to practice the bird wing cycles.|
|Initial rough poses/sketches of the smaller birds flying at the beginning of the animation.|
|Flying ducks key pose practice.|
From creating these rough sketches I realised there were some alignment issues with the flying ducks (including the right duck's feet) and that the wings needed a lot of work in the smaller birds, from here I then began to try out the key poses in Flipbook.
