The overlap and followthrough of this walk cycle was ok, I would call it moderate. The first thing I noticed is that the torso leans to the same side the entire time. This is bad because the torso is supposed to shift over from side to side and correspond with the weight bearing leg. The arms are also pretty stiff. It’s good that the fingers are moving, but their movements don’t correlate to how the hands are moving and how the arms are swinging. Also, the chest and hips are lacking front to back and up and down motion.
The spacing of this video is moderate as well. The rigs arm movements consist of extra swings that are a little unsightly. I also noticed that it’s front arm sticks back and the knees have a little pop to them. There is also a point in the animation where the rigs neck and head suddenly sink into the characters body.
The arcs in your video are also fairly moderate. There is a regular wobble consistent in your character. Also, the feet in the animation lack a ball roll which almost makes your rig look flat footed.
I would grade timing the same as everything else as well, moderate. There are multiple timing issues. Everything is just swinging with no rhyme or reason. It does not feel like a whole but instead like a bunch of swinging disconnected parts. Also, parts of the animation randomly speed up and slow down.
There is literally no squash and stretch so I will give that a poor. That’s all there is to say about that.
