I've put together a clip of some of my animation tests. The first clip is to try and convey natural and fluid movement with a pendulum. The rest of the clips are a basic walk cycle. I even moved the shoulders and swayed the body to help push the action. The last clip, I added head and eye movements. The walk seemed very similar to the Robert Patrick walk from "Terminator 2".
The cycles are a little fast because I realized later that I was working on them with the frame rate set at 12 frames per second, not the standard 24 fps. So that's why it's a bit fast. I'll correct that next time.
