Trying out an Animation

[Link]

Hey guys, I'm trying my hand at making my first animation for this sprite:


(Inspired by the style of tachi and fuchikoma's avatars, but not exactly)

Well, here it is:





I'm not really sure what to do, because the legs are the same color I'm having trouble showing that the legs are alternating stepping, instead of one just moving over and over. Disregard some of the smaller details for now, like the eyes bobbing as he moves, as I'd like to just focus on how he's moving.

The animation itself is supposed to be him kind of creepily tiptoeing along, but that probably doesn't look like it because I'm a terrible animator (and, you know, the whole leg thing) and it's faster than it should be.

Any help is appreciated.
