Walking is always the hardest part... For me atleast. I usually try to copy other sprite leg animations.
I can see you were going for a SMW style walk, which never looked like a walk to me.
Try animating it 1, 3, 1, 4
1,3,1,4:
Yap, better.
So anything else, or move on to jump?
I dunno, maybe make it so he isn't stepping with one foot over and over again?
Thats what I 'm having trouble with. The middle pose was suppose to make it look like the feet were going in a circle.
Try throwing 2 in it, like 1, 3, 1, 4, 3, 2,
Oh and I edited the middle position.
Edit:I'm just going to edit 2 into the jump, it doesn't really work with the animation.
Turing, and jumping.
Epic Wes did the crouch, but I edited the hat on it.
It looks like he's sticking his head into his pants.
I don't like the falling pose. The way you made mario in this style, it seems his arms should be very short and stubby. They shouldn't be able to stretch out that far away from his body. Maybe it's just the angle, but I think it looks weird if his arm is only away from his body in one pose on one spite of the whole sheet. It ruins a lot of consistency and stick out oddly to me.
Ha ha. That is a really funny set of Mario sprites. All I can say is..... It's nothing like I have ever seen before. xD
