Zombizzle

Made this zombie guy for an art test. Didn't end up getting the position, but I wouldn't have made this otherwise, so it's still a win for me. 

Anything glaringly wrong here?

It needs a few transition frames at the end so the transition from the last frame to the first isn't that obvious, but I guess you already knew
If the arms moved a little bit after the rest of the body it would look less stiff I think.

pretty good! love me a good zomboid stumble. i second adding some more frames though, the drag from the left leg doesn't quite read as well as it could. one solution i see could be to refiddle it towards the camera so his foot "rolls" with the movement.

for an idea of what i mean, look up pictures of people doing ollies and study what the front foot is doing, it makes for a more believable shift in motion to keep the walker steady between lurches.
I'd embed one but it's hard to do on mobile.

Not bad! Hard to do with just 4 frames.

Anything glaringly wrong here?

Yes. As for animation, the limp, his leg should stretch out on the landing and the knee bend when it is releasing from the floor. Like a normal step.
Also, anatomy, I'm not an expert on the subject but where are his hips? I can't find them in each frame :p . He has a very tall upper body and a very short upper left arm.

I tried to address these issues, and on top of that I also:
- Delayed the hand coming down by one frame, which makes sense if you'd try it yourself and also makes the animation more fluid by not putting all of the action on the same frame
- Rotated the head backwards, because it seemed funnier like that
- Tried to stop his back/butt from going all over the place

That is all I remember doing.. Have a look
