Added some more animation, particularly to the head and torso as advised. I made some tweaks to the right hand as it wasn't 'flapping' as much as the left and was too slow. I also added another layer of clouds which will go faster than the background and some camera shakes to help with the illusion of free fall.
I think it looks okay actually. Waiting for feedback as I'm sure there is something I can do to improve it but so far it's gone better than expected. The intention of this was to see if I could create the illusion of falling so that me and Rachel would know how to do it in the final animation. It is absolutely vital we get this looking decent because otherwise, if we don't get it at least believable, the whole animation will suffer for it and look 'floaty' and wrong.
