Ok, i just did a walkcycle which i havent done in ages.
I chose to do it in 2d because i knew that would be one i would do worst:) I could probably spend 20min on a 3d rig, and make a pretty decent walk. But i think that a little bit of struggling would help me remember the mistakes along the process. If that makes sense:P
First i drew up a plane for the dude to walk on. And then a made 4 keyframes spread evenly across 12 frames. The keyframes only shows the guys head, torso and feet.
I then filled in the in-between frames to smothen the animation. Trying to keep in mind how the feet would react, which way they would go etc...
Then, i added hands. First on the keyframes, and followed the same process of adding inbetweens.
I tried to exaggerate the movements on both hands and feet.
The front hand seem to go too far out from the body, it looks tensed.
I added colors on one foot and one hand.
I think maybe i should have had a slower movement of the hands when they cross.
