Photoshop: animating from scratch

During my last photoshop tutorial we looked at creating an animation that's just based in photoshop using a timeline animation rather than a frame animation. This allowed us to work at a specific set frame rate rather than selecting how long each frame stays on screen. This is a much more professional way of woking and I felt it created much smoother results.
First I tried animating a simple pendulum that breaks and turns into a bouncing ball. This was a good way to test drawing in photoshop and getting a feel for how best to animate at 12fps.
Once I'd got my bearing a bit with the software I decided to try and do something more interesting. By making the face the background i could animate the bouncing eye separately making my life much easier and the animation appear smoother.

After this I tried to animate using a background which I had drawn previously and manipulate the background to be part of the animation. This was a lot more challenging as there were many different elements to consider at one time. I found labeling all of my layers in photoshop really helpful to avoid confusion whilst switching between frames.
