I think your major problem here is the angle. It's hard to mimic that animation from that perspective. Also, his feet never come off the ground; they need to be lifted when moving forward.

A friend of mine, who's a far better spriter than I am, took a look at it and says the torso is far too long. I quote: " It's like two children standing on each other's shoulders pretending to be Mario." Gotta be honest, I'm getting that impression, too.
