First time spriting a walk cycle, help appreciated

[Gwen]

Mm, yeah, as the title says, I'm working on a walk cycle for a game and due to my relative inexperience in that area, I could use some crits.



WIP, obviously. I don't want to finalize the shading until the animation is sound.

My concerns:
Some of the frames look kind of stupid (here's looking at you frame 3) but seem to flow okay in the animation. Is this bad?
Should his torso move? What's the best way to go about that?
It's supposed to be isometric, but somewhere along the line it sort of stopped looking isometric. 8/

C+C?

I'm sorry if this comes off as completely random, but do you go to Dakota State University? That looks so much like the main character for a game a team of seniors are working on
If you were looking for walk cycle help on a platformer type I could help, but I've no experience with isometric sprites. For the most part though, the animation seems pretty smooth, even if a frame by itself looks odd.
