I'm politely stating that I don't see your point. No need to get defensive.
You are allowed to criticize, as I'm allowed to criticize your points. Am I not?
You were simply stating it doesn't look like a run, but you weren't saying how it could look like a run.
Why are you moving the animations like that? I don't see how that is relevant to my point. Did you think "faster" meant moving animations left and right more quickly?
The simple notion of walking and running. The concept is to move forward and move forward faster.
He will not stay in a simple spot in game, he will move in the stage. Is a mockup.
This one illustrates it better.

The slow version looks like he's doing a lot of effort to move very few inches, looks like he's losing his breath.
The fast version looks proper.

The 3d version is a jumpy jog. Guillotin3 was
inspired by it, but as I see it is not a 1:1 base.
Running = jumping forward a bit with each step. (both feet should be in the air for a small period of time before landing)
Yes he does it in his 3d version, but do all heavy people run like that? in real life?
Walking, or in this case marching = there's no period of time when both feet are in the air. One foot moves you forward, one foot leaves the ground, the one moving you forward goes back, the one that left the ground "lands" and it's in front of you, you move forward with it, the one in the back leaves the ground, etc. . There's always one foot on the ground when walking.
People can drag their feet while running. More likely so if they are heavy. Not everyone is an athlete.
I still think the animation is great and it fits Earthquake a heavy guy, he drags his feet in his official walking animation (also used as his backwards walk). Is a
hurried up movement, not a marathon run, it even adds a funny element and clumsiness.
That is all. To be honest this looks like arguing for the sake of arguing. I don't want to partake in it.
I thought we were giving proper feedback, is a shame you want out of the conversation, because I have done a lot of running and walking cycles, I like doing them. And was curious why you see it as a walking and how would you easily fix it, but ok.
