ooo what do we have here

if he doesnt know how to tell me how to fix it, then how can i tell?

That's...kind of your job as an artist. If he can be specific, that's great, but otherwise, you are the one who has to figure it out. I don't think you should ever discourage people from pointing out what they see about your work. It's always good to know how others are perceiving it. If you can't figure it out, then that's your problem, not his.

disregarding that, i made a running animation, but it is still in progress

Have you considered turning his head in profile view during the run cycle? It's always weird to see side-view running bodies but 3/4 view heads.

Also the head keeps jutting left and right, but I don't think it should...it seems sort of disconnected from the flow of the body because of it?
